This patch ensures that 64-bit shared objects are put in and found in a
subdirectory named "64".  Note that the changes to the
Lib/distutils/tests/test_build_ext.py and .../test_sysconfig.py avoid running
tests that fail due to this patch.  As the patch is Solaris-specific, it is
not suitable for upstream.
