I can only tell you why this doesn't work. The "Extra CFLAGS" are _not_
used to set the CFLAGS environment variable. We use wrapper scripts for the
compiler and basically fake different defaults. The configure script will
never see the options you set here. Anything else doesn't work reliably.
Some packages ignore the specified CFLAGS, other always add '-g -O2' etc.

There is currently no way to force a different optimization level globally.
We have it for debugging (PTXCONF_TARGET_DEBUG_*). You'll need to hack
ptxdist to do the same for optimization.
