    Pass GUILE down to subdirectories
    
    When I enable cgen rebuilding in the binutils-gdb tree, the default is
    to run cgen using 'guile'.  However, on my host, guile is guile 2.2,
    which doesn't work for me -- I have to use guile3.0.
    
    This patch arranges to pass "GUILE" down to subdirectories, so I can
    use 'make GUILE=guile3.0'.
    
            * Makefile.in: Rebuild.
            * Makefile.tpl (BASE_EXPORTS): Add GUILE.
            (GUILE): New variable.
            * Makefile.def (flags_to_pass): Add GUILE.
