[Mesa-dev] last call for autotools

[Marek Olšák]

Most assertions and checks are enabled, because NDEBUG is not defined, but
DEBUG is not defined either, which is a Mesa-specific definition.

The default debug build for autotools is debugoptimized (-g -O2 -DDEBUG).
meson changed that behavior by removing -DDEBUG. Autotools doesn't have
what meson calls "debug", which indicates that most people don't want to
use "debug" much. People who wanted to -O0 had to set CFLAGS. Now people
who want the autotools debug build have to add -DDEBUG into CFLAGS.

On top of that, I discovered a 3rd issue with meson:
* meson --reconfigure doesn't re-run llvm-config.
