Building octave-3.2.0 fails when linking octave, due to undefined references to functions in libpthread. Adding -lpthread to LDFLAGS in Makeconf manually makes it build properly.

Sorry, I meant adding -lpthread to FLIBS in Makeconf.
Though your case seems to suggest it was not '--as-needed' problem. *** This bug has been marked as a duplicate of bug 277068 ***
