Better support for lib64 and Debian multiarch
If CMAKE_SIZEOF_VOID_P is not set from the outside, it checks for the
existance of /usr/lib64, and if it exists, SIZEOF_VOID_P is set to 8.
For multiarch, if this is debian and
CMAKE_${LANGUAGE}_LANGUAGE_ARCHITECTURE has not been set, it globs
for the files in /lib, and uses the first one which matches
CMAKE_LIBRARY_ARCHITECTURE_REGEX.
