Bug#368366: no line number info even with DEB_BUILD_OPTIONS="nostrip noopt debug"

[Steve Langasek]

This patch /should/ be enough to get mesa built with debugging symbols:

Unfortunately, upstream's build system is too fragile for this, and setting
CFLAGS in the environment appears to override other CFLAGS that need to be
set in order to build the drivers correctly.

More investigation needed.
