We see a regression with PowerPC:

-----8<-----
/builds/linux/arch/powerpc/kernel/cpu_setup_6xx.S: Assembler messages:
/builds/linux/arch/powerpc/kernel/cpu_setup_6xx.S:124: Error: unrecognized opcode: `sym_func_start_local(setup_g2_le_hid2)'
/builds/linux/arch/powerpc/kernel/cpu_setup_6xx.S:131: Error: unrecognized opcode: `sym_func_end(setup_g2_le_hid2)'
make[4]: *** [/builds/linux/scripts/Makefile.build:382: arch/powerpc/kernel/cpu_setup_6xx.o] Error 1
----->8-----

This is seen only on PowerPC with GCC 8, GCC 13, Clang 17, Clang nightly, on:
* allnoconfig
* tinyconfig
* mpc83xx_defconfig
* ppc6xx_defconfig
(at least)

Reproducer:

tuxmake \
--runtime podman \
--target-arch powerpc \
--toolchain gcc-8 \
--kconfig tinyconfig
