I think this would be better if it just explicitly listed the libraries to keep
and then deleted everything else.

Also, this shouldn't be disabled when use_chromium_linker == 1 (since
use_chromium_linker==1 for chrome_apk).

[Feng Qian, 2014/03/18 00:07:01]

Listing libraries to keep will have issues with building multiple targets, if
the list only has libraries of current target, it will delete libraries of other
targets.

I am not sure if it will work.

Removing 'use_chromium_linker' check. It reminds me that I forgot to include
changes in Linker.java :)

Oh right, because this is deleting the ones in <(SHARED_LIB_DIR) too. How about,
along with making this only affect libchromeview we also move the action into
that target or the chrome_apk target (i.e. it shouldn't really be needed for all
apks).
