Ports: Allow verbose argument in build_all.sh

This patch allows for a verbose argument to be passed
so that the build output of the individual builds
is printed to stdout instead of /dev/null to help with diagnosing errors

If the verbose argument is not passed the old behaviour is preserved
and the build output is printed to /dev/null
