 ticket: new
 subject: osf1: get proper library dependencies installed
 target_version: 1.6.1
 tags: pullup

 The LDCOMBINE setting for Tru64 left out $(CFLAGS), which meant the
 -pthread option wasn't being passed in, so the libraries didn't
 indicate a dependency on the pthread library despite the fact that we
 need it unconditionally (if thread support is enabled).  Including
 $(CFLAGS) should fix this.

 Our own binaries get linked with -pthread anyways, so they build okay,
 but other binaries trying to link against or load our libraries could
 have problems.
