This is for ppc building the libstdc++-64bit rpm.  It needs to recognize
that we use shared libgcc to activate the symbol versioning.  But -lgcc_s
is not enough as the 64bit libgcc_s is called libgcc_s_64.  This hunk reflects
similar code in trunk and tries to find out the real name of the gcc_s library.
