tl;dr: with gcc

make OPTIMIZE="-O0 --coverage" OTHERLDFLAGS="--coverage"

Replace coverage-report with:

if [ "$COVERAGE" -eq 1 ]; then cover -ignore_re '/CORE/\w+\.h$'; fi

In fact you need to (for single-dir distros, i.e. not PDL) set OPTIMIZE and LDDLFLAGS to the values shown. For multi-dir ones, you need to override perl's %Config to achieve this. Also, gcov2perl needs running from the repo top-level to preserve filename structure, but gcov needs to be run in each subdir else it gets confused.
