Why are our ``CFLAGS`` equal to ``-g0 -O0``? #75

There's a more in-depth explanation of why are we using these?

If I remember correctly it was to speed up the compile time for GCC and reduce debugging symbols.

I would have to check through the commits

Per commit c8d6a00cca1105206ac622f3752c113871a1b39c

CFLAGS was set to -g0 -O0 to disable optimizations to speed up compile time of GCC. GCC built for the toolchain /tools is not the GCC used in the final MLFS system. Therefore, any optimizations would not be utilized in the final system.

Gotcha! Thanks Derrick!
