[PATCH BUG #1236 0/3] Unify ldd/ldconfig for all multilib eglibcs

[PATCH BUG #1236 0/3] Unify ldd/ldconfig for all multilib eglibcs

[Lianhao Lu]

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 f94b781695cd8fa387daff16ecbf3987a0883018:

[PATCH BUG #1236 1/3] utils.bbclass/multilib.conf: Added misc supporting functions.

[Lianhao Lu]

1. Added variable MULTILIB_VARIANTS to store all the instance variants
for multilib extend.

2. Added function all_multilib_tune_values to collect the variable
values for all multilib instance.

That branch is against poky, making it really hard for people to test the patches against the oe-core repo you're submitting it against. Please base patches against the oe-core repo when you send them to the oe-core mailinglist.
