Cross-compilation isn't supported for BLS12-381

[kobigurk]

paired depends on raw-cpuid which, although mentions it cross-compiles to iOS/Android, depends on x86/x86_64. That causes these kind of errors when trying to cross-compile:

50 |         let result = unsafe { self::arch::__cpuid_count(a, c) };
   |                                     ^^^^ could not find `arch` in `self`

What target_arch are you using? are you using the latest version of paried, I recently fixed a bug around this.

I used w/e @nikkolasg introduced to the repo. I'm committing a makefile with cross compilation tools soon that you can try out :)

@dignifiedquire check out #16. You can enable bls12-381 in the Makefile and see the error.
