- Subject: [committed] Fix linking of static openmp applications on hppa*-hp-hpux11*
Attempting to link an openmp as a static executable currently fails
on hppa*-hp-hpux11* because librt is not included in the link. librt
is only available as a shared object, so it's technically not possible
to build a completely static openmp application. However, it is still
useful to minimize the number of shared libraries when debugging openmp
applications.
There are also link order issues with libpthread and libc, so I decided
to handle this case in LIB_SPEC.
Tested on hppa2.0w-hp-hpux11.11 and hppa64-hp-hpux11.11. Committed to trunk.

* pa64-hpux.h (LIB_SPEC): Link against librt when building static
openmp applications.
* pa-hpux11.h (LIB_SPEC): Likewise.
