noarch_libs.patch

Description of problem:
As part of a change for Fedora 27, I have written a patch for the erlang spec
file that will modify the Erlang VM to also search in /usr/share/erlang/lib for
noarch libs. I am attaching a patch I wrote that uses sed in the spec file to
append this new path just before the archful libs in the search path.

I have tested this patch with ejabberd by moving one of its dependencies
(p1_utils) into the new /usr/share/erlang/lib. Without this patch ejabberd
fails to start, but with the patch it starts up successfully.

Once we have this patch applied, we just need to modify the RPM macros to use
the new path for noarch packages and we'll have the change completed.
