Using 'pahole' needs to be disabled on MIPS as well in order to avoid
host depended config file adaptions which let the build fail.

In commit 382e4ea5aef35e748466e635845ee05d01ab96db
  "ptxdist: version bump 2022.12.0 -> 2023.02.0"

the generic kernel build rule was changed to consider disabling the use
of the tool 'pahole'. But the mips arch has their local build rules and
thus, do not consider 'pahole'.

So, commit 6401964d92d713d5ea2004f00483d006bbf9522b
  "platform-mips: kernel: version bump 5.15 -> 6.2"

does not update the 'pahole' setting and building the BPS with '-q' always
fails due to kernel configuartion file adaptions.

+Fast development
+================
+
+Sometimes a quick test should be done: a new kernel feature or a tool
+should be tested on a real target.
+
+If the target suports USB OTG (or peripheral mode) or network, 'fastboot'
+can be an easy to use solution.
+
+'fastboot' support
+------------------
+
+For a fast development or testing cycle you can use 'fastboot' via
+USB or networt to transfer the required parts to the target system.
+
+Here we want to run a Linux kernel and a corresponding root filesystem,
+without writing target system local memories againg and again for each
+development or test cycle.
+
+In this text, we transfer the required files to the target system
+which only needs to run a 'fastboot' capable bootloader.
+
+Since we want to use an initramfs as the kernel's root filesystem, we
+have some requirements to the target system's free memory. The bootloader
+keeps up to 512 MiB of memory to add files to its own RAM disk. The
+512 MiB is valid for a physical memory size of 1 GiB and above. With less
+physical memory it is always 50 % of the available physical memory.
+Keep an eye on the size of the initramfs file if it fits onto the
+bootloader's RAM disk. Reduce its size on demand.
+
+Note: the 50 % rule is only valid for the time the bootloader runs. After
+      starting the Linux kernel, 100 % of the physical memory is available.
+
+Some settings are required to make it work smoothly.
+
+Linux kernel
+------------
+
+- CONFIG_BLK_DEV_INITRD=y
+
+And one of the supported decompressors:
+
+- CONFIG_RD_GZIP
+
+Note: the required decompressor depends on the used compression method for the
+      initramfs selected in the BSP. See below.
+
+Bootloader
+----------
+
+The 'bootm' command must support initrd/initramfs:
+
+- CONFIG_BOOTM_INITRD = y
+
+If your target system has an OTG connector, you should enable 'fastboot' on
+the gadget interface:
+
+- CONFIG_USB_GADGET = y
+- CONFIG_USB_GADGET_FASTBOOT = y
+- CONFIG_CMD_USBGADGET = y
+
+If you want to use 'fastboot' via network instead (or in addition) to the
+USB interface, you should enable this channel as well:
+
+- CONFIG_NET_FASTBOOT = y
+
+Since we want to transfer large initrd/initramfs files, 'fastboot' requires
+'sparse' feature support:
+
+- CONFIG_FASTBOOT_SPARSE = y
+
+And we want run the downloaded files, so we need:
+
+- CONFIG_FASTBOOT_CMD_OEM = y
+
+BSP
+---
+
+Create a initramf of the root filesystem:
+
+- PTXCONF_IMAGE_ROOT_CPIO = y
+
+You need to select a compression method for the initramfs file in relation to
+the selected decompression support in the Linux kernel. See notes above.
+
+- PTXCONF_IMAGE_ROOT_CPIO_COMPRESSION_MODE_GZ = y
+
+The generic behaviour changes when the Linux kernel starts an initrd/initramfs
+and it tries to start '/init' instead of an init processes in subdirectories.
+If you can change the kernel's command line, you can restore the generic behaviour
+by adding 'rdinit=/sbin/init'. If not, you can create a softlink at '/init' pointing
+to '/sbin/init via:
+
+- PTXCONF_ROOTFS_INIT_LINK
+
+Optimisation
+------------
+
+Some BPS settings do not make sense regarding used in an initramfs instead
+of a persistent target system local memory. For development or testing some
+settings should be changed, to reduce the file sizes and boot time.
+
+The Linux kernel will be transfered separately, so it makes less sense to
+have it in the root filesystem as well. This will reduce the size of the
+initramfs.
+
+- PTXCONF_KERNEL_INSTALL = n
+
+Some 'rc-once' jobs are useless in an initramfs and only increase the
+boot time again and again:
+
+- PTXCONF_GLIBC_LDCONFIG_RC_ONCE = n
+- PTXCONF_MACHINE_ID_RC_ONCE = n
+
+If possible, disable the whole rc-once step:
+
+- PTXCONF_RC_ONCE = n
+
+If you don't need ssh, you can disable its key generation as well:
+
+- PTXCONF_OPENSSH_SSHD_GENKEYS = n
+
+Preparations
+------------
+
+'fastboot' requires to divide large files into smaller chunks, if their
+size hits some threshold. In this case, there are some additional requirements
+to the size of the file itself: its size must be a multiple of 4 kiB.
+
+Note: if this additional requirement isn't met, the error message is
+      missleading and states about an 'invalid value' after the first
+      transfer.
+
+Most of the time the initramfs file hits the threshold. Thus, it must
+be 4 kiB aligned::
+
+   dd if=<platform-dir>/images/root.cpio.gz of=cpio.gz conv=sync bs=4096
+
+Target
+------
+
+Enable the 'fastboot' feature on the target system::
+
+   usbgadget -a -A /kernel(kernel)c,/devicetree(devicetree)c,/initrd(initrd)c
+
+Host
+----
+
+Download the three parts into the target system::
+
+   fastboot -i 7531 flash kernel <platform-dir>/images/linuximage
+   fastboot -i 7531 flash devicetree <platform-dir>/images/<devicetree>
+   fastboot -i 7531 flash initrd cpio.gz
+
+If you have no '/init' in your root filesystem, you need to define the
+init executable to be run by the Linux kernel::
+
+   fastboot -i 7531 oem exec 'global linux.bootargs.ramfs=rdinit=/sbin/init'
+
+In the final step, just start the already downloaded files::
+
+   fastboot -i 7531 oem exec -- bootm -o /devicetree -r /initrd /kernel
+

Thx, series applied to next.
