On some Linux systems, "-lrt" exposed pthread-functions, so that linking with -lrt was seemingly enough to make a program that uses pthreads to work. However, when linking libpq, the dependency to libpthread was not marked correctly, so that when an executable was linked with -lpq but without -pthread, you got errors about undefined pthread_* functions from libpq. To fix, test for the flags required to use pthreads earlier in the autoconf script, before checking any other libraries. This should fix the failure on buildfarm member shearwater. gharial is also failing; hopefully this fixes that too although the failure looks somewhat different.
