Around Linux 5.11, upstream started introducing checks that execute
"pahole --version" for feature discovery (e.g. [1]).
However, when building with BR2_LINUX_KERNEL_NEEDS_HOST_PAHOLE Buildroot
only lists host-pahole in LINUX_DEPENDENCIES, so it isn't available for
the configure step when using BR2_PER_PACKAGE_DIRECTORIES. This results
in the host pahole being used (resulting in host-dependent behavior), or
no pahole being detected at all when the build host doesn't have it
(which will then disable Kconfig options that require it).
Fix this by adding host-pahole to LINUX_KCONFIG_DEPENDENCIES.
A similar issue occurs when running "make linux-menuconfig" and friends
because PATH deliberately gets stripped when pkg-kconfig.mk builds
x_CONFIGURATOR_MAKE_ENV. Explicitly pass the pahole path to fix this.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at https://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC.
