It’s possible, but inconvenient: you’d have to modify (guix build gnu-build-system), or to add a GCC wrapper that appends “-march=foo”. However, because you’d be building things differently, you wouldn’t be able to use substitutes provided by mirror.hydra.gnu.org. Likewise, binaries built on your machine may be unusable on other machines, if you use -march=native or similar. Ludo’.
