ldb FTBFS on hurd:

ldbadd: ./pthread/../sysdeps/generic/pt-mutex-timedlock.c:70: __pthread_mutex_timedlock_internal: Assertion `__pthread_threads' failed.

Attached patch fixes pthread linking issue (probably fixable in a better
way) but it keeps FTBFS'ing due to lack of record locking implementation.
