classes from say, /lib/geom, cannot be statically linked completely.
Moreover, those shared objects may require other shared objects (i.e.
for geom, libraries like -lmd, -lcrypto).
The libs_so extension to crunchgen fixes this by allowing some libraries
to be linked in dynamically. This requires that a copy of rtld and the
shared libraries be made available to the crunched binary, and so is not
suitable for all environments. Crunchgen configurations which do not
use the 'libs_so' keyword are unaffected and produce identical binaries
with and without this commit.

or 'env MAKEOBJDIRPREFIX=... make' depending on the setting of
MAKEOBJDIRPREFIX in the environment. In any case this line kills the
original value of ${MAKE}. When during buildworld a new make is built (as
is the case during the upgrade) this causes a wrong make to be picked up
(the first one in the path). Use the same technique as Makefile.inc1:
create a MAKEENV variable and a CRUNCHMAKE that calls ${MAKE} with that
MAKEENV prefixed. Use CRUNCHMAKE instead of MAKE throughout the generated
makefile. This leaves the original ${MAKE} undisturbed.

correct .CURDIR setting, e.g. src/bin/csh.

"int _crunched_%s_stub(int argc, char **argv, char **envp)"

Make sure we pass $(BUILDOPTS) to the `clean' target
so that `make clean' works on the same set of object
files. Otherwise, we may end up with an incorrectly
built and up-to-date object file.

/usr/obj hardwired in the code, now you can override it
with a command line option or MAKEOBJDIRPREFIX env. variable.
The above is useful to build picobsd-specific objects in some other
place than /usr/obj
While at it, fix documentation and change a few sprintf -> snprintf.
This allows build flags to be specified for a particular program from
within the crunch.conf file, eg:
prog ppp
special ppp buildopts -DNOKLDLOAD -DNOINET6 -DNONAT -DNOATM
This adds '-DNOKLDLOAD -DNOINET6 -DNONAT -DNOATM' to make targets
related to ppp when determining which object files to build and
when calculating dependencies and building the targets.
a per program basis.
This has now been added in the following way:
* Harness the make header file that's specified with the -h argument:
- Allow the user to define $(OPTS) to specify make arguments that should
be added to every program target.
- Allow the user to define $(prog_OPTS) to specify make arguments that
should just be added to the build of 'prog'.
* Make sure that $(OPTS) and $(prog_OPTS) are defined when looking through
each program's make file to determine which object files to crunch.
* When building the crunchgen makefile add $(OPTS) and $(prog_OPTS)
to the depend and build rules for $(prog_OBJS).
makefiles (for use with picobsd among other things).
See the manpage for details, but:
* -h makefile-include-name
can be used to specify a file to include in the makefiles
generated by crunchgen . This is a good place to specify make
variables such as RELEASE_CRUNCH, NOTHIS, NOTHAT and the like.
* special progname objvar variable_name
in the crunch config file declares a different variable than
OBJS to be used to get the list of objects.
* crunchgen now looks first for Makefile.<progname> in the current
directory to override the makefile in <progname> source dir.
This in many cases avoids the need to patch the original makefile
if the above two features are still not enough.

like so;

When building a release, RELEASE_CRUNCH is defined for a `make' of
the objects required by the crunch of each program. The object list
is still obtained in the same way, so you must make sure that all
objects are built (empty if necessary) by this make. ppp/Makefile
provides an example.
