adds support to build emscripten packages using nix:

example usage:

- nix-env -I nixpkgs=../somewhere/nixpkgs -f default.nix -iA emscriptenPackages.libxml2
- nix-env -I nixpkgs=../somewhere/nixpkgs -f default.nix -iA emscriptenPackages.json_c
- nix-env -I nixpkgs=../somewhere/nixpkgs -f default.nix -iA emscriptenPackages.zlib
- nix-env -I nixpkgs=../somewhere/nixpkgs -f default.nix -iA emscriptenPackages.xmlmirror
