Hi Guix !

This fix work for some computers, but some test will fail on other computers,
I'm not sure why.

You were looking at test failures, not build failures, right?

In the end do you think changing LLVM versions had an effect at all?

Thanks for investigating.  :-)

Yes, tests could failed at execution.

Yes, 'llvm' has been update to 6.0.1, but Julia need llvm on version 3.9.
With 'llvm@3.9.1' I'm able to build Julia but with 'llvm@6.0.1' the build phase
failed.

Julia compiler development is on older LLVM's. There are few languages that
keep up with LLVM (Clang is core, and Dlang being one of the exceptions).

Understood.  I’ve applied the patch.

For posterity, using ‘llvm’ (version 6.0), Julia failed to build with:

--8<---------------cut here---------------start------------->8---
    [34mCC[0m [33msrc/codegen.o[0m
/tmp/guix-build-julia-0.6.0.drv-0/julia-0.6.0/src/codegen.cpp:39:45: fatal error: llvm/Target/TargetSubtargetInfo.h: No such file or directory
compilation terminated.
make[1]: *** [Makefile:144: codegen.o] Error 1
--8<---------------cut here---------------end--------------->8---

Thanks!
