aac1b9fa39 Allow multiple image activators to run on the same execution by changing
imgp->interpreted to a bitmask instead of, functionally, a bool. Each
imgactivator now requires its own flag in interpreted to indicate whether
or not it has already examined argv[0].

Change imgp->interpreted to an unsigned char to add one extra bit for
future use.

With this change, one can execute a shell script from a 64bit host native
make and still get the binmisc image activator to fire for the script
interpreter.  Prior to this, execution would fail.

168c6df708 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).
