    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.
