Subject: [PATCH] dpkg-buildflags support
* dh_auto_build, dh_auto_configure, dh: Set environment variables
listed by dpkg-buildflags --export. Any environment variables that
are already set to other values will not be changed.
Closes: #544844
* Also, support DEB_BUILD_OPTIONS=noopt, by changing -O2 to -O0.
