Patch to fix gcc operation with HP DCE threads

[John David Anglin]

Here is a patch to fix a long standing problem with threads under hpux 10.X.

Wed Apr  5 13:44:35 2000 John David Anglin <dave@hiauly1.hia.nrc.ca>
* configure.in (hppa1.1-*-hpux10*, hppa1.0-*-hpux10*): thread_file
should always default to `single' because of multilib implementation.
* configure: Rebuilt.
