Nathan Chancellor 653d51504f powerpc: xor_vmx: Add '-mhard-float' to CFLAGS
[ Upstream commit 35f20786c481d5ced9283ff42de5c69b65e5ed13 ]

arch/powerpc/lib/xor_vmx.o is built with '-msoft-float' (from the main
powerpc Makefile) and '-maltivec' (from its CFLAGS), which causes an
error when building with clang after a recent change in main:

  error: option '-msoft-float' cannot be specified with '-maltivec'
  make[6]: *** [scripts/Makefile.build:243: arch/powerpc/lib/xor_vmx.o] Error 1

Explicitly add '-mhard-float' before '-maltivec' in xor_vmx.o's CFLAGS
to override the previous inclusion of '-msoft-float' (as the last option
wins), which matches how other areas of the kernel use '-maltivec', such
as AMDGPU.
