Fix TestBigEndian configure error

It turns out that when MacPort (and possibly HomeBrew) are installed
on a MacOSX system, the "intl" library
is first found in a non standard location:

  HAVE_LIBINTL:FILEPATH=/opt/local/lib/libintl.dylib

Compared to, for example, libraries "m" and "util" which are found
in "/usr/lib":

  HAVE_LIBM:FILEPATH=/usr/lib/libm.dylib
  HAVE_LIBUTIL:FILEPATH=/usr/lib/libutil.dylib

Since CMAKE_REQUIRED_LIBRARIES variable used for the different configure
tests was updated with the name of the library instead of the full path
to the library, the first compile test was failing complaining that
it couldn't be linked against the "intl" library:

"/Applications/CMake 2.8-10.app/Contents/bin/cmake" -E cmake_link_script CMakeFiles/cmTryCompileExec1536614598.dir/link.txt --verbose=1

Specify full path of "crypt", "nsl", "m" and "util" libraries

Anticipate issue similar to the one fixed in previous commit 6043a5d by
using full path for libraries specified using only a name.
