 pthread_create() doesn't work as expected.

 give up, environment is inconsistent.

I consider this is vendor bug.  Sun should provide a consistent
environment.

The configure script always tries to use the environment flags
provided by the installer (ie: the user) to allow the installer
to specify alternative thread packages.  If a pthread_create()
exists in the installer provided flags, we expect it to work.

Placing
	ac_cv_func_pthread_create=${ac_cv_func_pthread_create='no'}

into an empty config.cache before running ./configure would disable
this test.

I've updated our Solaris hints to include the above as the
recommended workaround.

Suggestions on how to beter handle this vendor bug that do not
restrict the use of alternative thread packages would be welcomed.
