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.

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

If no arguments are passed to a subcommand that requires arguments,
error out before we deref a null pointer in the check for max length.

Thanks to otis in IRC for the bug report.

Check for invalid length or more than max length for the interpreter, instead
of the validity of the string pointer holding the interpreter.

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).
