Before filing a bug, please check whether it has been fixed since the
latest release. Search the issue tracker and check that you're running the
latest version of Go:

Run "go version" and compare against
http://golang.org/doc/devel/release.html  If a newer version of Go exists,
install it and retry what you did to reproduce the problem.

Thanks.

What does 'go version' print?

go version go1.3.2 freebsd/amd64

What steps reproduce the problem?
If possible, include a link to a program on play.golang.org.

1. build on a platform where where clang is called "cc"
2.
3.

What happened?

What should have happened instead?

Please provide any additional information below.

See:

https://code.google.com/p/go/source/browse/src/cmd/go/build.go#2104

        if strings.Contains(a[0], "clang") {

On platforms where clang is called "cc" (because it's the only compiler by
default), this code fails. In order to get clang detected properly I had to set CC=clang.
