[svn-r26082] Moved the high-level library checks up to the same place where

Fortran and C++ are checked. This will make it easier to
handle threadsafe/high-level combinations later.

Also changed the default of --enable-pthread to 'check' and
removed yes/no behavior. If you ask for thread-safety, you
can't disable Pthreads...

Part of HDFFV-8719

Tested on: jam (configure only)
