Bug fixing [YOCTO #1236].
1. Collect all the values for RTLDLIST for the current multilib
configuration to modify the ldd scripts.
2. Collect all the values for KNOWN_INTERPRETER_NAMES for the current
multilib configuration. Set the correct ld.so names for ldconfig to deal
with the multilib configuration.
