OK. I can confirm you that changing just this single line:

==========================
fixes the compilation under MIPS, and hopefully in the rest of
platforms (if you're interested, I'll let you know if it's really the
case, but building one single file in a MIPS emulator took me ~30mins,
so it'll take days!!!).
Please, apply that patch upstream. You can also replace all those "&&
!defined()" by a few "|| define()" if you are sure on which platforms
cpuid works... (x86 & x86_64?).
Thanks and... have a happy new year!
