Bug#775235: Repeatable failure to start on i386 running under kvm

came across launchpad bug #1360241 [1] which discusses the same error.
There it comes from ubuntu-ui-toolkit tests.

There they did revert their mesa package to depend on llvm-3.4 instead
of llvm-3.5.

So did I and recompiled mesa to use llvm-3.4 (see attached patch).
And with these packages installed the error message was gone and the login
screen is shown and a login possible.

Going back to current jessie packages depending on llvm-3.5 lead to
getting the error message again.

Kind regards,
