I think I've found that there are still some problems in parsing options.

1. The following command:

  GUIX_BUILD_OPTIONS="--no-grub" guix package --help

gives the following error:

  guix package: error: no-grub: unrecognized option

So it makes impossible to use GUIX_BUILD_OPTIONS env var or did I miss
anything?

2. The manual says that ‘guix package’ «supports all the common build
options that ‘guix build’ supports» and the following command works
perfectly:

  guix build --system=i686-linux hello

However, the following command:

  guix package --system=i686-linux --install hello

gives an error again:

  guix package: error: system=i686-linux: unrecognized option
