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.
