gnustep-base on OpenBSD mips54

[Sebastian Reitenbach]

Hi,

I just tried to compile gnustep-base on my OpenBSD mips64, but did not
worked out on OpenBSD -current mips64 platform. I got errors like this:

Due to the hint of a fellow OpenBSD developer, who suggested attached
patch, I was able to at least compile it, whether everything works as
expected, I'll see next year ;)

The second and third hunk of the patch are those that fixed the problem
for me.

Just defining USE_ATOMIC_BUILDINS  (is the D in BUILD a typo?) did not
helped, then I had errors in the linking stage afterwards, about
unresolved references.

Patch is against latest gnustep-base stable.
