I'm seeing build failures on a wide range of the selftests in -next due
to this patch.  The build fails with:

aarch64-linux-gnu-gcc -fno-asynchronous-unwind-tables -fno-ident -s -Os -nostdli
b \
        -include ../../../../include/nolibc/nolibc.h -I../..\
        -static -ffreestanding -Wall za-fork.c /build/stage/build-work/kselftest
/arm64/fp/za-fork-asm.o -o /build/stage/build-work/kselftest/arm64/fp/za-fork
In file included from za-fork.c:12:
../../kselftest.h:108:8: error: unknown type name ‘bool’

probably fixable by adding ‘#include <stdbool.h>’

I'm using gcc-14, full build log at:
