[rfc/testsuite/fortran] add fortran programs

[Michael Chastain <mec.gnu@mindspring.com>]

Hey, gdb.fortran has no actual FORTRAN programs in it!
I'm going to fix that.

My plan is:

  (1A) Add gdb.fortran/Makefile.in.  The test subdirectories have
       trivial Makefile.in files that don't do much, but it's actually
       necessary to have one of these and hook it up to configure
       and configure.in so that $build/testsuite/gdb.fortran gets
       created.
  (1B) Add skip_fortran_tests to lib/gdb.exp.

  (2)  Add a simple "hello world" test.  The very first test is
       going to KFAIL, because the gdb command "start" does not work
       with FORTRAN!

  (3)  Shake that out for several days.

  (4)  Add a test script for gdb/648, from David Lecomber's work.

dejagnu 1.4.4 is set up so that language "f77" runs a compiler named
"g77".  If "g77" is not available on some targets, then we can add those
targets to "skip_fortran_tests".  Look at testsuite/lib/gdb.exp
procedure "skip_cplus_tests" for the idea.

Here is the patch for (1A) and (1B).  I haven't tested this yet.

I'll give this plan 48 hours for comments, then commit the first
patch.  Note: "yo, I'm really busy but I want to talk about this
before you charge into the implementation" is a perfectly valid
comment.
