collect2 compiles C with g77 !

Thanks.  Odd that nobody else is having this problem.

It looks like collect2 thinks there are EH frame tables that need
initialization for various objects in libgcc2, which I guess is a
side effect of compiling libgcc2 with -fexceptions.

  >     1. Make collect2 always invoke gcc
This would be my first thought; though it looks like collect2 is
setup (for a reason?) to use whatever driver that called collect2
(ie g77, g++, gcc)

The one problem I can see with this is it might end up invoking cc1
with fortran options.  The Fortran folks have said this would would
be desirable so that g77 foo.f bar.c would do the expected thing.

I don't think we want to stray down that path.  That would mean
including much of varasm.c/final.c in collect2 -- gross.
