[PATCH 4/5] binfmt-support /proc locking workaround

[otavio at ossystems.com.br (Otavio Salvador)]

From: Otavio Salvador <otavio@ossystems.com.br>

When binfmt-support package is installed, it calls update-binfmts
--import and it does lock the /proc breaking the whole building
process. To workaround it we call the update-binfmts --disable to
unlock it just before unmount /proc.
