I am now doing that. :)

Long ago in a galaxy far away, when I first joined the project, I noticed the variable being set in the /etc/profile.d/qt.sh script that came with the Slackware qt3 package. I presumed the variable was important. Of course, that script is for run time and not for compiling. Over time I have been learning to strip many environment variables from within my build environment, but that one slipped through unnoticed until this mess surfaced.

Maybe we should have a short snippet in our wiki with what are appropriate environment variables, which ones to avoid, and what is appropriate for CXX/CFLAGS?
