The nbsd architectures in GDB don't use bsd-uthread, only obsd.

Looking at cvsweb for OpenBSD, it seems that OpenBSD switched the default
threading library from a uthread-style libc_r to a LWP-based librthreads
for its thread support in 2012:

This seems to have been released in OpenBSD 5.1?  I believe that the older
uthread-library last shipped in OpenBSD 5.0 in 2011.  Presumably Mark (cc'd)
can confirm?
