elfutils: towards uClibc support: solve memcpy problem
elfutils uses some strange internal alias of memcpy in glibc, so workaround this when building with uClibc. Heavily based from work done by Stefan Fröberg, but with many further modifications by Thomas Petazzoni.

+Provide a compatibility alias __memcpy
+
+For some reason, libelf uses the internal glibc alias __memcpy, which
+doesn't exist in uClibc. Add a manual alias so that the build can
+proceed with uClibc.
