[PATCH] uml: fix dynamic linking on some 64-bit distros

With Paolo 'Blaisorblade' Giarrusso <blaisorblade@yahoo.it>

The current UML build assumes that on x86-64 systems, /lib is a symlink
to /lib64, but in some distributions (like PLD and CentOS) they are
separate directories, so the 64 bit library loader isn't found.  This
patch inserts /lib64 at the start of the rpath on x86-64 UML builds.
