Good that I asked, because I understood "TUNE_PKGARCH is the granularity
it needs" as the exact opposite ;-}

The "if possible" part is where it gets tricky. There's this comment
next to the DEPENDS saying "libgcc is required for the target specific
libraries to build properly" and I simply have no idea how obviously
it'll break when removing the dependency in go-cross.

Anyway, I'll proceed down that route by rewriting the go.inc. Note that
Richard correctly pointed out that the inclusion of go-1.8.bb in
go-cross-1.8.bb isn't particularly clean, making such a change a bit
more complicated. But I don't want to move content around too much just
for this, so I'll leave the cleanup to the go maintainers.
