given as a nested attribute set isomorphic to all-packages.nix,
where the value for each attribute is a list of platforms on which
to build the package. For instance,
{
wine = ["i686-linux"];
xorg = {
libX11 = ["i686-linux" "x86_64-linux"];
};
}
says that the "wine" attribute in all-packages.nix should be built
on "i686-linux" only, while the "xorg.libX11" attribute should be
built on "i686-linux" and "x86_64-linux".
There are some aliases for common platform groups (currently "all"
for all supported platforms, "linux" for all supported Linux
platforms).
