Bug#915004: RM: trackballs [armel] guile-2.2 is not available on armel

[Jeremy Bicha]

Package: ftp.debian.org
X-Debbugs-Cc: trackballs at packages.debian.org
Affects: src:trackballs

guile-2.2 doesn't build on armel currently. Therefore, please remove
trackballs from armel.

trackballs has no reverse dependencies in Debian. (games-arcade and
junior-games-gl are arch:all packages that recommend trackballs.)

See https://bugs.debian.org/883778 for more details about the guile armel issue.

Thanks,
Jeremy Bicha
