commit r17-4957-g65bca052a5364f16ecdf9d45c0414fd02a5d4559 Author: Uros Bizjak <[email protected]> Date: Wed Sep 30 11:41:57 2026 +0200 config: Update config.rpath from gnulib Sync config.rpath with build-aux/config.rpath from gnulib (commit e93789db7e86). The old copy invoked egrep, which GNU grep 3.8 and later warns is obsolescent. As a result, every configure run printed checking for shared library run path origin... egrep: warning: egrep is obsolescent; using grep -E into the build log. The updated script uses plain grep for these checks. The update also picks up other upstream changes. ChangeLog: * config.rpath: Update from gnulib.
