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:

Nix, the purely functional package manager
Nix is a new take on package management that is fairly unique. Because of its purity aspects, a lot of issues found in traditional package managers don't appear with Nix.
To find out more about the tool, usage and installation instructions, please read the manual, which is available on the Nix website at http://nixos.org/nix/manual.
