Way back during early dejazilla days, the "check-local" target was
needed in order to liberate test results, regardless of pass/failure
of the dejagnu suite. To make that work, an "execrc" wrapper was
interposed between make and dejagnu/runtest, to turn everything into
a pass rc=0.
Dejagnu support was removed in 2022, so this execrc hack is not needed
any more. Tests that fail, especially the early
systemtap.base/environment_sanity.exp one, should stand out better
in buildbot reports.
