Patch from Ralf Corsepius <corsepiu@faw.uni-ulm.de>:

  The main topic is replacing the hard-coded values for HAS_MP and
  HAS_RDBG in custom/*.cfg with per-bsp configuration-time autoconf checks
  (This is the patch I had mentioned before earlier this week).

  CHANGES

  * HAS_MP removed from custom/*.cfg, replaced with configuration time
    autoconf check
  * HAS_RDBG removed from custom/*.cfg, replaced with configuration-time
    autoconf check
  * NEW: c/src/make/bsp.cfg.in, takes configuration-time checked per-bsp
    values (i.e. HAS_MP, HAS_RDBG), gets installed as
    $(prefix)/<bsp>/make/bsp.cfg
  * NEW: default.cfg includes bsp.cfg - this change is backward
    compatible.
  * IMPORT_SRC: apply VPATH instead for ts_386ex/i386ex subdirectory
    Makefile.ins
  * HACK: a bug in acpolish mis-handles addtions to makefile variables
    which are enclosed in gmake conditionals:
    c/src/lib/libbsp/m68k/ods68302/start302/Makefile.in
  * Apply inline_dir, HAS_MP and HAS_RDBG for avoiding configuration of
    unneeded subdirectories in various configure.in files.
  * Several minor changes in Makefile.ins and configure.ins, wrt. to the
    order of including *.cfg and defining Makefile variables
