PR 65462 points out a problem with the way that the gccgo version of
go get handles dependencies, a problem due to the fact that with gccgo
the source code of the standard packages is not normally available.
This patch from Lynn Boger fixes the problem. Bootstrapped and ran Go
testsuite on x86_64-unknown-linux-gnu. Committed to mainline.
