Can not build packages with conflicting dependencies

[jenrik]

If a packages has a dependency that conflicts with an already installed package the build fails. Pacman offers to replace the already installed package with the dependency but it automatically receives a no, a solution would be to automatically replace conflicting package without asking

I encountered the problem while building pam-selinux, because pambase-selinux conflicts pambase

I have been looking for possible solutions. Pacman doesn't have a option for automatically replacing packages that are in conflict with already installed packages, so the only possibly solution I have found yet is to add an options for building a package interactively.
That shouldn't be to hard to implement the primary thing to do is not parsing --noconfirm option to pacman
