How to remove package and all dependent packages from EL branch?

[Peter Lemenkov]

Hello.
I've got bugreport that Erlang doesn't work on EL6 PPC64 achitecture.

https://bugzilla.redhat.com/show_bug.cgi?id=958953

I don't have resources to fix this issue, and nobody volunteered to
fix it so far, so I'd like to limit Erlang, and Erlang applications
and libraries on EL6 to x86/x86_64, where they works for sure. It's
not the only issue with Erlang and PPC64 - it also has limited support
for Java which prevented Erlang-Java bridge from being built
successfully. Reducing Erlang on EL6 to architectures where it works
even allows me to drop one patch and remove a couple of ifdefs from
spec so this will simplify things a bit.

Is there any documentation which describes the process of package
removal from a particular EL hardware branch?
