Actually, you asked for two different software renderers:
--with-dri-drivers=swrast produces lib/swrast_dri.so based on classic
swrast, --with-gallium-drivers=swrast produces lib/gallium/swrast_dri.so
based on llvmpipe/softpipe. 

Presumably both are built before and after the change(s) in question,
they merely changed which one ends up installed / picked up first at
