To be fair, I believe it has been the case only for 2 weeks now (implemented in
r269096).

Hello Mehdi,

Thank you for bringing this to our awareness. I've been looking into the 
3.8 release of LLVM. Would you happen to know if r269096 was part of 
this realese?

lli running on my system is capable of handling unnamed global 
variables, so I'd imagine so.

u at x1 ~> lli -version
LLVM (http://llvm.org/):
   LLVM version 3.8.0
   Optimized build.
   Built May  7 2016 (15:37:50).
   Default target: x86_64-unknown-linux-gnu
   Host CPU: broadwell

Cheers /u

No it isn't in 3.8.
(I also mentioned in my email that it happened two weeks ago, which is obviously
far after the 3.8 release).
