[llvmlinux] compile error x86

[Marcelo Sousa]

Hello everyone,

I'm getting an error after doing make in the x86 directory related to
inline assembly:

/home/marcelosousa/Research/llvmlinux/targets/x86_64/src/linux/arch/x86/include/asm/bitops.h:70:16:
error: ambiguous instructions require an explicit suffix (could be 'btsw',
'btsl', or 'btsq')
                asm volatile(LOCK_PREFIX "bts %1,%0"
