[gentoo-dev] new eclass: golang.eclass for compiling go packages

[William Hubbs]

All,

It turns out that we do need a second eclass for Go packages.

this eclass is meant to provide a common src_compile function for
packages written in the Go programming language.

Let me know what you think.

Thanks,

William
