OpenBSD is pretty much a proof of concept port. I decided to not put too
much time in it till OpenBSD/x86 got ELF, and updates its binutils a bit.

However if you have a specific problem, I will investigate it.

To make it easier, in the report

- Name your versions of as and ld.
- submit a working program that shows the bug.
- describe compiler options, and possible other conditions that trigger
  the bug.
