They're not exactly dynamically linked, but PIE is used by default
in OpenBSD (opt-out rather than opt-in; every program uses PIE unless
specifically told not to).

So, even though the files are statically linked, they still use
ld.so which handles the relocation.

The more accurate fix would probably be using "-fno-pie" rather than
"-static". (-static implies -fno-pie).
