I don't know if this is planned for Fedora 21 too, but I suggest upgrading llvm to version 3.5.0, as it resolves this error with FlightGear (tested with a local build of mesa+llvm-3.5.0) :

Hmm, llvm-3.5 seems to break ghc 7.6.3 badly on armv7hl (ie in Rawhide).
So I would prefer to wait with llvm-3.5 f21 until that is sorted out.
We are also in the F21 post-Beta phase now so it is rather late
for such a major version bump.
llvm34 is now available in rawhide and working with ghc on arm.

Transaction check error:

I got the same multilib conflict:
$ rpm -q llvm-devel
$ yum update
Transaction check error:
file /usr/share/llvm/cmake/LLVMConfig.cmake conflicts between attempted installs of llvm-devel-3.5.0-5.fc21.i686 and llvm-devel-3.5.0-5.fc21.x86_64
Note this is live in updates, not just updates-testing any more.
As a workaround, it's fine for me to just remove llvm-devel.i686 for now...
This multilib problem still exists today:
file /usr/share/llvm/cmake/LLVMConfig.cmake conflicts between attempted installs of llvm-devel-3.5.0-6.fc21.i686 and llvm-devel-3.5.0-6.fc21.x86_64
As a Mesa developer, I need both packages to test changes with a variety of (32-bit and 64-bit, closed source and open souce) games and test suites.
This message is a reminder that Fedora 21 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 21. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora 'version'
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.
Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 21 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
Fedora 21 changed to end-of-life (EOL) status on 2015-12-01. Fedora 21 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
Thank you for reporting this bug and we are sorry it could not be fixed.
