New review comment by ahesford on void-packages repository

Comment:
Instead of uniformly disabling tests, consider adding `configure_args+="-Ddisable_tests=true"` inside a `[ -z "$XBPS_CHECK_PKGS" ]` test (see, for example, the `opencv4` template) to allow those tests to run with `xbps-src check` or `xbps-src -Q pkg`.

If the tests fail for other reasons and can't be fixed, that's a different matter.
