cmd/go: fix failing gccgo cases in TestScript/build_overlay

The 'go install' command does not support the -gccgo flag.
(I'm not sure why, but it doesn't.)

gccgo also uses system-native assembly syntax instead of cmd/compile's
Plan 9 derivative. I've added an assembly file that seems to work on
Linux, but I haven't tested it on other platforms; if it fails on
other platforms, we can refine the test as needed.

Fixes #42688
