it's not set, default to -Os (so it's not hard coded into the binary.)
Generate a makefile by default that does all object file builds in local
subdirs by binary (i.e. bad144 gets built in $OBJDIR/bad144) via a reach over
make. (Sets .PATH and .CURDIR and does a make for the objects needed in that
dir).
Add a -o option that does the old behavior of searching for obj files by
querying the various object environment vars and searching. Without this
option none of the objdir special options, environment vars, etc will have
effect.
Document all the changes in the man page (and specificly note that without -o
none of the objdir functions take effect).
1) Always do a make clean before building objects in any directory. This
is wasteful, but there's really no other simple way to cope with the
fact that the compilation settings (e.g. CFLAGS) appropriate for the
non-crunched build of a program may not be appropriate for the crunched
build. If the objdir magic in make didn't rely upon the presence of an
"obj" or "obj.${MACHINE}" symlink, we could abuse it to handle this but
unfortunately, it does.
2) Override $DBG to cause object files to be built with -Os. We can't emit
"DBG?=" into the generated makefile because of order-of-inclusion issues
with the system Makefiles; the result would be that the default setting
(currently -O2) would always be used instead of -Os. If you're crunching,
you almost certainly are doing it to get a smaller executable (!) so -Os
is almost certainly appropriate for you.
1) Include bsd.sys.mk so we pick up DESTDIR changes to fine .h files.
2) Only set STRIP if it's unset.
3) Generate .cro files rather than .lo files. .lo now is used for "local
objects" - obj's for the host machine not the target machine.
the machine type a run-time decision a la make. Also, use ${LD}
for the linker, not ld.
Note: you will have to delete the crunchgen cache file for these
changes to take effect.
2) Add __RCSIDs where apropriate.
3) WARNS=1, and clean up sources for WARNS=1 (including replacement of
a mktemp with a mkstemp even though it was probably safe...)
4) Some other small cosmetic changes
