fgrep has been deprecated in favor of grep -F for a long time, and the
next grep release (3.8 or 4.0) will print a warning of fgrep is used.
Stop using fgrep so we won't see the warning.
We can't hard code grep -F here or it may break build on hosts w/o GNU
grep. autoconf documentation contains a warning about this issue and
suggest to use AC_PROG_FGREP and $FGREP, but these are too overkill in
the specific case: there is no way "debian" could be interpreted as an
non-trivial regex, so we can use a plain grep here.
gcc/fortran/ChangeLog:
* Make-lang.in: Use grep instead of fgrep.

LGTM but i cannot approve it. I'd say this one is trivial and obvious
so you could sneak it in under the "obvious" rule..
Thanks for the patch!

I concur, this could also have been obvious.
Anyway, OK for trunk, and
