Since you’re using regular expressions here:

1. Escape the dot with a backslash
2. Anchor the end of the string (since you already anchored the beginning) with
$.

'^base_paths_linux\\.cc$'

Same on the next line.

You didn’t answer my question about execinfo being an additional build
dependency, but you might want to ultimately have a mode that doesn’t depend on
execinfo.

Oh sorry about that, missed it. Yes libexecinfo is a clone of the backtrace
facility found in glibc.
