This is a long standing bug in PCL. We agreed at pointclouds.org long
ago, to use optimized flags as default, but adhere CFLAGS, if they are
set. At some point this option was removed and I had no time till now to
patch it in again (patches welcome). The version in the PPA is compiled
in debug mode to prevent this, so this would be an easy way for the ROS
maintainers as well, but ideally we should adhere dpkg-buildflags.

Cheers Jochen
