go-cross: avoid libgcc dependency 

libgcc gets compiled differently depending on the tune flags for the
target. That dependency would make go-cross also tune specific and
prevent sharing it between different machines using the same
architecture.

For example, MACHINE=intel-corei7-64 and MACHINE=qemux86-64 shared the
same go-cross-x86_64, but compiled libgcc differently.

The libgcc dependency gets inherited from go.inc, but does not seem to
be necessary for go-cross (compiling go-helloworld still succeeds).
The dependency is left in go.inc conditionally, just in case that it
really is relevant for the various on-target recipes which inherit
that.

Because go-cross*.bb includes go*.bb, moving the DEPENDS into a .inc
file that only gets included for the target recipes doesn't
work. Reshuffling the content of three .bb files seems too intrusive
at this point.

(From OE-Core rev: 58149a7be4172074349951aaf5af95fa40fd4bdb)
