Does this issue reproduce with the latest release?

Yes

What did you do?

If possible, provide a recipe for reproducing the error.
A complete runable program is good.
A link on play.golang.org is best.

What did you expect to see?

ok cmd/link/internal/ld 114.969s

What did you see instead?

I'll submit a small fix as the failing test is timing out on gcc instead of checking its availability as elsewhere using testenv.MustHaveCGO(t).
