Strip prebuilt shared library but not try adding gnu debuglink.
It would fail if you try run the adding gnu debuglink command if a
prebuilt is already stripped.

Build system can not find the dependent library if assigning a
multi-prebuilt which module name is different with it's library
file name as following:
PREBUILT_LIBS := libabc_debug:libabc.a

Add files included as prebuilts with "BUILD_MULTI_PREBUILT"
to be installed as part of the 'prebuilt' target.
