autoconf: Allow overriding CFLAGS/CXXFLAGS from outside.
As is normal for autoconf-based projects.
For example, it is a common use case to do
./configure CXXFLAGS=-O0
This did not work for nix until now, because the `CXXFLAGS=` declaration
would unconditionally erase what the user had specified.
The custom `OPTIMIZE` flag is removed, but the default `-O3` is retained;
autoconf would default to `-g -O2` by default otherwise as documented on:
