LLVM: use OpenBSD target code for AArch64

[Patrick Wildt]

Hi,

a clang binary using the AArch64 backend currently does not use
proper OpenBSD defines and specifics.  This is because we don't
tell clang to use OpenBSD target info if it encounters an AArch64
target.

This diff makes LLVM do all the OpenBSD stuff for AArch64.

ok?

Patrick
