Joel Sherrill effc2c4e6b Patch rtems-rc-4.5.0-6-cvs.diff from Ralf Corsepius <corsepiu@faw.uni-ulm.de>.
The patch contains:

  * build variants support
  * Reworked make-exe custom/*.cfg for all targets (Should be
    self-explanatory, may still be incomplete)
  * Several fixes to custom/*.cfgs related to setting debug flags
  * Fixes to some bsp_specs for BSPs which apparently have never been
    build with debugging before ;)
  * pc386.cfg fix attempts (cf. my mail from earlier today)
  * Updated ampolish (No need to run it, the patch contains the result
    from having applied it)

Known bugs/deficiencies related to this work:

  * "make [clean|distclean]" support is still incomplete (e.g. "make
    clean" does not delete all Depends-o-*)
  * Completely untested for linux/posix and hppa.
  * Build failures of i960 BSPs (make VARIANT=DEBUG) - I guess, they are
    not related to this patch.
  * Successfully tested for all sh, sparc, i386, ppc, m68k BSPs (make
    VARIANT=DEBUG)
  * make VARIANT=PROFILE not supported by all BSPs (I don't care :)
  * make VARIANT=DEBUG failures below tests/ for some BSPs (e.g. gensh1),
    because of the tests's binaries being too large to fit into the target
    memory layout.
