Auto-disable use of pthread_mutexattr_setkind_np due to compile error…

…s (Revised-Revised)

The code being disabled here causes a compilation issue on Ubuntu Jammy Jellyfish. (undefined reference to `pthread_mutexattr_setkind_np`) The best I can tell, https://bugs.launchpad.net/ubuntu/+source/glibc/+bug/2003146 explains this somewhat.

This workaround likely hasn't been necessary for the past 20 years, if glibc "converted to git" repositories are any indication (see for instance https://github.com/lattera/glibc/blob/d82e4c7bb231c9e0f835bd46467563ac3b56cebe/linuxthreads/sysdeps/pthread/pthread.h ).

And indeed, anyone who would be attempting to run OpenOffice on such a system would likely encounter issues with the other varied libraries in use.

Unfortunately other compilation issues prevented me from performing a full test, but osl mutex tests pass at least.
