Subject: [PATCH] darling: fix src

Darling has a case conflict which means that its src hash will be
different between case sensitive and case insensitive file systems.
This is not ideal and the only way around it is basically to remove
the offending files from the output. I use fetchzip here to do that
but I hope there is a better fix available eventually.
