This allows the use of chroot and/or jail environments which depend on
interpreters registed with imgact_binmisc to use emulator binaries from
the host to emulate programs inside the chroot.

kldfind() only matches kernel modules, so if you link imgact_binmisc directly
into the kernel, binmiscctl can't find it, tries to load it, and errors
out with:
Can't load imgact_binmisc kernel module: File exists
A quick search of other base commands shows that the correct procedure is to
call modfind(), and then try kldload() if that fails.

may make Coverity think that other negative values of cmd (used
as an index) are possible. Testing < 0 is a more common idiom
in any case.

This is not properly respecting WITHOUT or ARCH dependencies in target/.
Doing so requires a massive effort to rework targets/ to do so. A
better approach will be to either include the SUBDIR Makefiles directly
and map to DIRDEPS or just dynamically lookup the SUBDIR. These lose
the benefit of having a userland/lib, userland/libexec, etc, though and
results in a massive package. The current implementation of targets/ is
very unmaintainable.
Currently rescue/rescue and sys/modules are still not connected.

execution to a emumation program via parsing of ELF header information.
With this kernel module and userland tool, poudriere is able to build
ports packages via the QEMU userland tools (or another emulator program)
in a different architecture chroot, e.g. TARGET=mips TARGET_ARCH=mips
I'm not connecting this to GENERIC for obvious reasons, but this should
allow the kernel module to be built by default and enable the building
of the userland tool (which automatically loads the kernel module).
