[svn-r6386] Purpose:

    Bug fix

Description:
    The "system scope" for threads isn't supported on all platforms.

Solution:
    Add detection of this feature to the configure script and check for
    "H5_HAVE_SYSTEM_SCOPE_THREADS" in the appropriate places.

Platforms tested:
    modi4 w/threadsafe
