llvm35 package for F23

[Jens Petersen]

Hi,

I prepared a llvm35 package for Fedora 23
(like the llvm34 package for F22) needed
for ghc-7.10 on armv7 (and eventually armv8),
since llvm-3.6 in Rawhide is too new.

https://bugzilla.redhat.com/show_bug.cgi?id=1223673

Note like llvm34, this package only includes
llvm itself and not clang, etc.

Is someone able to help review it, please?

Thanks!
Jens

ps If it help I can offer a review swap
if it is something not too obscure.
