  • -fprofile-dir shouldn't be used because on the g++ command line because it has different behaviour with different versions (w.r.t. where the output gcda file ends up).
  • The gcda and gcno files may end up in the same directory as the object file or in the current working directory.
  • The output of the gcov call in collect_cc_coverage may be ".gcda.gcov.json.gz" or ".gcov.json.gz" (as well as the original text file for much older GCC versions).

Also re-enable the test for Ubuntu 20.04 pre and postsubmits.

Fixes #16229

Hmm, looks like there are still some test failures
