Added patch to revert commit adding -mt for pthread support

This patch effectively reverts commit
curl/curl@74fdc11
adding -mt for pthread support on HP-UX. The commit only checks for the
host OS and does not take into account which compiler is used. Since we
are using gcc, it does not work for us.
