When building with clang-8 the frame size limit is hit:
../arch/powerpc/lib/xor_vmx.c:119:6: error: stack frame size of 1200 bytes in function '__xor_altivec_5' [-Werror,-Wframe-larger-than=]
Follow the same approach as commit 9c87156cce5a ("powerpc/xmon: Relax frame size for clang") until a proper fix is implemented upstream in clang and relax requirement for clang.
