[OE-core] [PATCH v3 1/8] go-cross: avoid libgcc dependency

[Patrick Ohly]

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 just in case that it is relevant for
the various on-target recipes which inherit that.
