go1.2

Though dirty, upstream recommended making the wrapper called 'gcc', and
put it in PATH. That is what is done for automated cross-compiled
builds. :-|

With that in mind, http://pastebin.test.redhat.com/179671 builds and
tests like a champ. :-|

What should we do? not use flags at all or use what we can until
upstream supports it?

Take care,
