+uclibc does not export __mempcpy like glibc so we alias it here.
+This patch may make sense for upstream but elfutils uses more
+glibc specific features like obstack_printf which are missing in
+uclibc they need to be fixed along to make it work all the way
+
+Upstream-status: Inappropriate[Elfutils uses more glibc specific features]
