Both SPARC support multiarch platforms (sparcv9 and sparc64) have the
a default assembly implemented memcpy. Since it should not be any
restriction about it them on the loader object and assuming they are
faster than generic ones this patch uses them for rtld objects.
Also, there is no indication neither on original patch [1] or in commit
message why the generic one where used instead of the sparc optimized
ones.
Checked on sparc64-linux-gnu and sparcv9-linux-gnu.
