The assembly sha512 code detects at runtime if it is running on a 64-bit
processor (PA2.0) and, if so, switches to 64-bit code.
However, when running under a 32-bit OpenBSD/hppa kernel, there is no guarantee
that the upper part of the registers will be preserved accross context switches
(or even userland->kernel boundaries), which causes this code to fail.
Wrap the generated code within #ifndef __OpenBSD__ in that case, to avoid
using the 64-bit code completely. (OpenBSD/hppa64, once stable, will not be
affected by this)
