    Fix shared library support on Android.
    
    This patch fixes two problems:
    1) A libtool library created with the -release option and no -version-info
       option was, when built with --enable-shared, installed without the
       symlink libNAME.so -> libNAME-RELEASE.so. This led to subsequent failures
       during "make install" of shared libraries that depend on it.
    2) Executables were created without a RUNPATH property. These executables
       then did not find their shared libraries when run.
    
    * m4/libtool.m4: On Android, fix library_names_spec and
    hardcode_libdir_flag_spec.
