Hi,
to do some release tests with iked we wanted to play^Wtest games/openra
over IPsec. Turns out that arm64 does not support lang/mono, but I have
gotten it to run. With the following diff, games/openra builds and I
can even play it.
This doesn't need to make release, so no worries. Would be nice for
others, but I myself run -current anyway.
The arch-defines.mk enables all mono-related packages. In gcconfig.h
OPENBSD needs to be checked so make sure in case it's AArch64, it
doesn't define NOSYS. Additionally apparently one has to check for
OPENBSD and __aarch64__ to define the mach type. Then there's another
AARCH64 block where OS-related stuff has to be defined. I simply used
the AMD64 block, but skipping ELFCLASS. In boringssl we need to have
the 'find aarch64 crypto accel' code as well. We don't have a nice API
yet to extract info, so let's for now only use NEON, which we require
on AArch64. As far as I can see, ucontext is sigcontext, so I provide
the same defines as FreeBSD but with sigcontext context.
I can try to get the diffs upstreamed.

Move aarch64 to the front of the list.
