[bug#73176] [PATCH] gnu: go-1.20: Build with gccgo-12 on some systems.

[Efraim Flashner]

* gnu/packages/golang.scm (go-1.20)[native-inputs]: Don't replace the
gccgo input on architectures bootstrapping go with it.

Change-Id: I26831b2bcfe623f6eb0ac7c16b463e5e873110e6

This should only cause rebuilds on riscv64 and ppc64le.
