Hi guix,

I get an 'Illegal instruction' error when running bsnes (on my X200).

$ guix environment --ad-hoc bsnes
$ bsnes
Illegal instruction

The makefile contains this:
https://github.com/bsnes-emu/bsnes/blob/4ea984b6886ecb61afc26c177eeced77e8582a44/bsnes/GNUmakefile#L17
(march=native when local)

I tried to patch it, but I don't know how to check if this is fixed.

I attach the patch here, on my laptop applied over 073b12d70d I get

guix hash -r /gnu/store/h2k0la0cyilfj7y7vm9r2zs1vi3wkiwy-bsnes-115
0298ajc60qpjhllyqv8gdb503bzg0rcd7pvigq22h7gm58d0g0sd

Thanks!
