Here is my first draft at adding support for the x32 and ARM
architectures; it is still pretty rough but I wanted to post
this in case anyone has either a x32 (32-bit ABI for x86_64)
or ARM system handy and wanted to help out with some testing.
I've run through the regression tests with the BPF simulator
but I haven't tested the library on a native ARM or x32 enabled
system yet; any help would be greatly appreciated.
Regardless, comments and feedback are always appreciated.

Paul Moore (10):
arch: disconnect the BPF arch token from the libseccomp token
bpf: support multiple architectures sharing the same BPF arch token
bpf: fix a problem with duplicate syscalls across architectures
arch: add basic x32 support
arch: add basic ARM support
tools: trim unsupported architectures from the BPF simulator
arch: rename arch-i386* to arch-x86*
tests: add support for the x32 and arm architectures
tests: add a test to exercise the various x86 architectures
tests: minor fixups due to the new arch support
