* messing with ldflags

* tweaking CGO

* tweaking some build flags

* Transitioned to different go base to try to head off problems with dynamically linked go binaries

* Added rpm to build, well, rpms

* allow easier overrides of GOOS/GOARCH for compile

* Fixed libnss-resolver config

* reverted ealrier go build tweaking
