objtool/x86: Fix elf_add_alternative() endianness
Currently x86 kernel cross-compiled on big endian system fails at boot with:
kernel BUG at arch/x86/kernel/alternative.c:258!
Corresponding bug condition look like the following:
BUG_ON(feature >= (NCAPINTS + NBUGINTS) * 32);
Fix that by converting alternative feature/cpuid to target endianness.
