Subject: The function '_dl_memset' should always be inlined regardless of the
optimization level chosen. This allows uClibc to be compiled with the latest
GCC-4.1.0. While tracking down the specific culprit causing the segmentation
fault of the dynamic loader with GCC-4.1.0 I was able to force inlining of
other functions such that I shaved 512 bytes off the size of the loader, yay.
Also fixed warning in 'dl-hash.c'.
