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.
