[Bug libfortran/26710] New: build failure on mactel: non-relocatable subtraction error for compile_options.c

["ccb at dl dot ac dot uk" <gcc-bugzilla at gcc dot gnu dot org>]

For the released 4.1.0, building runtime/compile_options.c (and others) fail on
i386 os x with a non-relocatable subtraction error.  A simple short term
workaround is to use -fno-common when building

After a successful build the specs are:
Using built-in specs.

- does not occur under ppc-apple-darwin8.5.0, even if the command line is cut
and pasted across.
