forked from Imagelibrary/rtems
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.
