#186 Fix build with "make --shuffle=reverse"

[Mattias Ellert]

This is a proposed fix for a bug originally reported to Debian:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1105407

"make --shuffle=reverse" runs the build targets i reverse order while still honouring the target dependencies stated in the makefiles. This exposes places where the makefiles depend on the default bulld order to build stuff in the right order without declaring dependencies between the targets properly.

The attached patch allows building with "make --shuffle=reverse".
