Is there a way to create a i686-musl voidlinux-installation?

I tried to do it after setting up xbps-src, installing binary-bootstrap like this:

$ git clone git://github.com/voidlinux/void-packages.git
$ cd void-packages
$ ./xbps-src binary-bootstrap

and using this command:

$ ./xbps-src -a x86_64-musl pkg base-chroot-musl

Results in:

[*] Updating `http://repo.voidlinux.eu/current/i686-repodata' ...

[*] Updating `http://repo.voidlinux.eu/current/nonfree/i686-repodata' ...

i686-repodata: 13KB [avg rate: 11MB/s]

Are there any other steps needed or is there another way to set up a i686-musl chroot installation?

I am using a gentoo (calculate) i686 live cd.

Thanks, Maarten
