[OE-core] [PATCH 0/3] Unify ldd/ldconfig for all multilib eglibcs for bug #1236

[Lianhao Lu]

This is a rebase of the original patches to oe-core branch instead of poky.

This series of patch allow all the eglibc(s) in the current multilib 
configuration have the same ldd/ldconfig settings. 

We put the dynamic loaders'(ld.so) names in the dictionary of "ld_info_all" 
defined 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 ldconfig 
binary.

The following changes since commit 2a41a311ddda11713296391050f3c2c1b2c1d3d3:
