Hi!

DT_RUNPATH worked the same way as DT_RPATH, ie. it could not be overridden
with LD_LIBRARY_PATH. Although the library could be found using
LD_LIBRARY_PATH and was opened by ld.so, it called open_path once again and
used the libs found through DT_RUNPATH.

	* elf/dl-load.c (_dl_map_object): If library was found using
	LD_LIBRARY_PATH, don't try RUNPATH list.
