doesn't pick up baggage from bsd.own.mk and bsd.prog.mk.
This stops parallel makes exploding because they try to build ${PROG} to soon.
Fixes toolchain/21563 (with change to src/distrib/common/Makefile.crunch).
Upped version of crunchgen to 0.3
then build the program itself.
This means that changes to any of the program source files cause the
crunched binary to be rebuilt.
Seems to work ok with the sysinst ramdisks.
two variables:
TOOLCHAIN_MISSING -- set to "yes" on platforms for which there is
no working in-tree toolchain (hppa, ns32k, sh5, x86_64).
EXTERNAL_TOOLCHAIN -- if defined by the user, points to the root of
an external toolchain (e.g. /usr/local/gnu). This enables the cross-build
framework even for TOOLCHAIN_MISSING platforms.
If TOOLCHAIN_MISSING is set to "yes", MKGDB, MKBFD, and MKGCC are all
unconditionally set to "no", since the bits are not there to build.
If EXTERNAL_TOOLCHAIN is set, MKGCC is unconditionally set to "no",
since the external toolchain's compiler is not in-sync with the
in-tree compiler support components (e.g. libgcc).
* Set MACHINE_CPU much earlier in bsd.own.mk, so that more tests in
that file can use it.
Even though envp is not the POSIX way of crawling through the environment,
this will hopefully save someone from having to scratch their head
really hard with a crunched program using envp.

crunchgen-created makefile with a partiallly complete build
(a situation which is more common than you think...)
solving the "parallel build" problem for crunchgen-created makefiles
needs to be done a different way...
fixes [toolchain/17012] from me.
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).
