### configure-scripts-override modifies the GNU configure scripts in
### ${WRKSRC} so that the generated config.status scripts never do
### anything on "--recheck".  This is important in pkgsrc because we
### only ever want to run the configure checks during the configure
### phase, and "recheck" is often run during the build and install
### phases.
