config.mk: default to `-O2` and `-DNDEBUG` (#435)

assertions are for debugging purposes, and so shouldn't be enabled for
"release" builds. disable it by default by using `-DNDEBUG`.

`-O2` on gcc/clang will result it slightly better binary. on tcc it'll
be ignored. and since -O is specified by POSIX there shouldn't be any
portability concern.

additionally add a (commented out) recommended debug build for gcc/clang
with address and undefined sanitizers turned on.
