Honor -brtl when using GCC on AIX

[Albert Chin]

When using GCC, libtool doesn't append -G to the link command-line
like it does for the IBM compiler (xlc/xlC). Patch against branch-1-5.

        * libtool.m4: Append -G to link command-line on AIX to
        honor -brtl on command-line (runtime linking). Already
        done for IBM C/C++ compilers.
