Currently, dist allows GOOS and GOARCH to appear as *any* substring in
a file name when selecting source files to go into go_bootstrap. This
was necessary prior to Go 1.4, where it needed to match names like
"windows.c", but now it's gratuitously different from go/build. This
led to a bug chase to figure out why "stubs_nonlinux.go" was not being
built on non-Linux OSes.
Change shouldbuild to require an "_" before the GOOS and GOARCH in a
file name. This is still less strict than go/build, but the behavior
is much closer.
