[m-rev.] diff: enable --warn-susppicious-foreign-code

[Julien Fischer]

I added the new option early last week; if anyone is not up-to-date let
me know and I'll hold off committing this.

-----------------------------------

Enable --warn-suspicious-foreign-code.

Enable the recently added --warn-suspicious-foreign-code warning by default for
the Mercury system.

configure.ac:
     Check that --warn-suspicious-foreign-code is supported by the bootstrap
     compiler

compiler/COMP_FLAGS.in:
compiler/DEEP_FLAGS.in:
compiler/LIB_FLAGS.in:
compiler/MDBCOMP_FLAGS.in:
compiler/SLICE_FLAGS.in:
compiler/SSDB_FLAGS.in:
compiler/PROF_FLAGS.in:
      Enable the option.

Julien.
