Enable assembler code only if it is known to work
on that operating system.
I'm too lazy to think how to make a good Autoconf test
for this and it's not that important anyway.
No longer define HAVE_ASM_X86 or HAVE_ASM_X86_64.
Inline assembler (if any) is used if a macro like
__i386__ or __x86_64__ is defined.
