Log message:
Real buildlink support for Go, hacked with wiz@.

Go packages now define a set of files to buildlink in their buildlink3.mk.
go-packages.mk no longer looks in ${PREFIX}/gopkg during the build. This
should also fix the spurious issues with rebuilds of .a files during bulk
builds of Go packages.
