veyron/tools/build: Support for cgo
The "C" package is a pseudo-package and thus attempts to import it will fail.
The lack of special handling for the C pseudo-package was causing tests on
OS X to fail with:
--- FAIL: TestBuildClient (0.03s)
impl_test.go:66: Import("C","",0) failed: cannot find package "C" in any of:
/Users/ashankar/veyron/environment/go/src/pkg/C (from $GOROOT)
/Users/ashankar/veyron/third_party/go/src/C (from $GOPATH)
/Users/ashankar/veyron/tools/go/src/C
/Users/ashankar/veyron/veyron/go/src/C
/Users/ashankar/veyron/environment/golib/src/C
since after https://veyron-review.googlesource.com/#/c/3698/
the package being built in TestBuildClient has a dependency on the C pseudo-package
on OS X
(veyron/runtimes/google/rt depends on C)
The test was passing on linux because the C dependency doesn't exist there.
But builds of real packages which require "cgo" would have failed.
