d0adbca274 Add RISC-V interpreter example
Now that RISC-V support has landed in qemu-user-static, add to the list
of examples in the binmiscctl(8) manpage.

caba8c7d3f Improve the binmiscctl manual page
- Use "Fl -" instead of "Cm --" for long options.
- Sort options alphabetically.
- Pet "mandoc -Tlint".
- Clean up the description of the "--interpreter" option.
- Clean up the description of the first example in the examples section.
- Use ".Bd -literal -offset indent" for all example code blocks for consistency.
- Use "Nm" instead of "Cm binmiscctl".
- Indent all examples for consistency.

9cede44051 Correct the binmiscctl(8) man page for powerpc64
Magic for powerpc64 erroneously specified ELFCLASS32 instead of ELFCLASS64.

4b5e2f8ea0 binmiscctl should use modfind instead of kldfind
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.

fe579263e0 Another attempt at resolving CID 1305629. The test of cmd == -1
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.

aa60f7a6de Revert r299584:
Mark usage() as __dead2 so that Coverity doesn't think that execution
  continues after the call and uses a negative array subscript.

b1f92fa229 META MODE: Update dependencies with 'the-lot' and add missing directories.
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.

numerous QEMU examples and explanations supplied by sbruno, with thanks
to Ingo Schwarze for help with the mdoc markup.  Code, text, testing,
proofreading, cinematography, stunts, and the haunting theme song

6d75644981 Add Stacey Son's binary activation patches that allow remapping of
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).
