Bug#646607: Subtle changes to the build system for libmowgli2 are included in the atheme sources.

[Mike Mestnik <cheako@mikemestnik.net>]

The atheme source doesn't include exactly libmowgli-2.0.0, instead it's
f4867ef73383f727d264c7d27c31e550c59a406d.  The changes are limited to
these files buildsys.mk.in and src/libmowgli/Makefile.

This command will spit out four patches that account for the changes, if
you have a git clone of libmowgli-2 from github:
git format-patch f4867ef73383f727d264c7d27c31e550c59a406d...libmowgli-2.0.0

libmowgli-2.0.0 is/was a tag pointing to
d6d4c017837440332fbb348e1ce2cd08bfe20b33 this is exactly what's in
libmowgli-2.0.0.tar.gz.

I'm unsure what these changes do or if they are only applicable if
libmowgli is an embedded code copy, but there it is.
