-Subject: [PATCH] Bindepend: Skip/warn unrecognised output from ldconfig
- (#5540). [skip-ci]
-
-ldconfig has started adding additional lines of output such as:
-
-    Cache generated by: ldconfig (GNU libc) release release version 2.33
-
-which caused regex parse errors. This particular line is now whitelisted
-as skipable. And any future unrecognised patterns will now issue
-warnings.
