[libgcc] Provide symbol to handle gcc's implicit calls to memset()

On some architectures (such as ARM), gcc will insert implicit calls to
memset().  Handle these using the same mechanism as for the implicit
calls to memcpy() used by x86.

- * gcc sometimes likes to insert implicit calls to memcpy().
- * Unfortunately, there doesn't seem to be any way to prevent it from
- * doing this, or to force it to use the optimised memcpy() as seen by
- * C code; it insists on inserting a symbol reference to "memcpy".  We
- * therefore include wrapper functions just to keep gcc happy.
