Commit Message

Pedro Alves July 23, 2026, 5:51 p.m. UTC 
  Add a new "make extract-results" target that regenerates the combined
gdb.sum/gdb.log from an existing outputs/ directory, without
re-running any tests.

This is handy after a parallel "make check" run to rebuild the
combined results by hand -- for example after tweaking
contrib/dg-extract-results.sh, to see the effect on the combined files
without a full testsuite run.
