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
