golang-cross: add ccache support

golang doesn't work with ccache. In the current state, a lot of parsing
happens where it'll grab the first string in CC or LD and uses that for
its builds. When ccache is enabled, it results in trying to do builds
with just ccache.

The brokeness is seen when building with apps that uses cgo, like docker.
To enable ccache to work, some string comparisons and changes to parsing
had to be made.
