I applied Paul's patch and it solves the problem whereby LANGUAGES is not
honoured, at least in this configuration. So if I type make LANGUAGES="c c++"
the build completes sucessfully (by skipping f77 and objc) and the resulting
c compiler seems to work (at least on a quick test, not a proper testsuite).
So I think this patch should be accepted (and thanks, Paul).

However, if you don't skip f77, the build still fails in the same spot. 
It looks as if gcc/f/runtime/configure still believes the compiler does not
work (or invokes it incorrectly) and gives up. Is the f77 runtime actually
supported in m68k-coff configuration? (I don't actually need it).

There is a minor installation bug: it seems --program-prefix is not honoured,
and the compiler is installed as m68k-coff-g++ and so on (I asked for m68k-g++).
Further, gcc is not installed at all.
