[svn-r13181] Added a configure check to prevent a failure on Cygwin.

It seems that while Cygwin supports the time command, it has trouble with
the syntax
srcdir="../../hdf5/test" time ./testhdf5
and complains.
The solution is to test the above case in configure and not to use the time
command if it fails; Cygwin is fine with
srcdir="../../hdf5/test"  ./testhdf5

Tested on Cygwin and kagiso.  This feature shouldn't be a major compatibility
problem since every platform but Cygwin is already fine with the current
syntax.
