Note that crunchgen's stub .c programs already have the code to use it:
"int _crunched_%s_stub(int argc, char **argv, char **envp)"
"{return main(argc,argv,envp);}\" >%s_stub.c\n",
Add $FreeBSD$ to allow the commit.

so the .lo files can be partially linked against libraries
which redefine symbols in the standard libs, or which reference
symbols in the objects.

This fixes a bug that I introduced around the time of 4.2-release.

longer includes machine/elf.h.
* consumers of elf.h now use the minimalist elf header possible.
This change is motivated by Binutils 2.11.0 and too much clashing over
our base elf headers and the Binutils elf headers.
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.
o strcpy() -> strlcpy()
o sprintf() -> snprintf()
o mktemp() -> mkstemp()
o use err() instead of errx() in out_of_memory() function since
errno will probably be set

/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).
