[svn-r17667] Bug 1656 fix:

Browse Source 
added a signal handler to the tcheck_version to intercept the abort signal from
H5check_version.  Some systems would prints extra messages and/or core dump if
the abort signal is not handled. This eliminates those unwanted side effect.

Tested: h5committested.
