RFC Modify ldd script for multilib.

This is part of the BUG #1236 fixing. Current there seems no way to get the dynamic loader(ld.so) names for all the ABIs configured in the multilib configuration during runtime. So we put the ld.so names in the dictionary "ld_info_all" in the file eglibc-ld.inc. This dictionary is indexed by the TUNENAME. To support a new ABI, new entry should be added into this dictionary along with the new ABI's TUNENAME.

The information in ld_info_all can be used for both ldd script, and the KNOWN_INTERPRETER_NAMES in the file ldconfig.h (which has not been done yet).
