Those who do not want optimizations should set the CFLAGS and CXXFLAGS

Previously, if we set --enable-debug we got -g -O2 which was pretty
much useless if you planned to use gdb (and why else would you use
--enable-debug?).
I'm using it because src/gallium/auxiliary/util/u_debug.h disables
assertions without DEBUG. Maybe that should be fixed to only disable
them with NDEBUG.
I'm realizing that people want a spectrum of debug vs. optimization
options. Personally, I'm only really interested in debug and release
modes (-g -O0 -DDEBUG versus -O2) so that's why I wanted
--enable-debug to set those flags.
I'm no expert on autoconfig so I'm not sure what the best solution is
for this.
Maybe we should all just use CFLAGS to set all our desired flags and
remove --enable-debug. Or if --enable-debug is kept, define it to be
shorthand for CFLAGS="something".
