be a good bit more successful at doing automated upgrades than the
previous aout-to-elf target, anyway. I'll MF3 in a couple of days
depending on how this does.
library directories: /usr/lib /usr/lib/compat /usr/local/lib and
/usr/X11R6/lib and adds any other directories that ldconfig knows
about, then removes any that are already aout directories (that is,
with aout as a component of the path) and passes this directory
list to the move_aout_libs.sh script to do the hack (believe it,
it moves libraries that are in use) work.
- Moved most of the guts of Makefile to Makefile.inc1 to become the
backend for the build system.
- The new Makefile doesn't suffer from problems including the wrong
sys.mk because it doesn't use anything in there or bsd.own.mk. So,
from now on, the proper build command is just `make world' (or
buildworld).
- The intermediate makefiles called Makefile.inc0 and Makefile.upgrade
fiddle with the OBJFORMAT and MAKEOBJDIRPREFIX variables so that
both aout and elf object trees can coexist. Makefile.upgrade contains
the aout->elf transition build.
- A cross build environment is now very close to reality. Specifying
TOOLDIR, setting OBJFORMAT and MAKEOBJDIRPREFIX allow that.
See the comments in Makefile for more info.
