[Bug target/43751] dsymutil is not called for fortran and, under some circumstances not for other FEs.

OK, it's not a regression - it never worked ;)

FSF 4.2 does not have the dsymutil spec.
FSF 4.3 does, but it fails in the same way as current trunk.

I'll manually compare apple-local-gcc-42/gcc/gcc.c with trunk/gcc/gcc.c as soon
as I have a spare moment.

As far as Fortran is concerned - this is missing from all versions of the spec
(so that needs fixing).  The problem at the moment is that adding  .f*|.F*
doesn't work (whether I expand the * manually or not).

In my current fix, I'm intending to remove that part of the spec - since, IMO,
it's non-obvious to create a debug sym file for "gcc foo.c -o foo  -g " and not
for " gcc foo.o -o foo -g "  (despite the reasoning behind that - which is
clear to compiler cognoscenti but not necessarily compiler users).

Of course, that alteration in behavior might not be acceptable to the Darwin
maintainers..
