I get this too on r600/Turks XT.

4638c993331b04c73453927cb0b9909fa0dbd282 is the first bad commit
commit 4638c993331b04c73453927cb0b9909fa0dbd282
Author: Eric Christopher <echristo@gmail.com>

    Remove the target independent TargetMachine::getSubtarget and
    TargetMachine::getSubtargetImpl routines.
    
    This keeps the target independent code free of bare subtarget
    calls while the remainder of the backends are migrated, or not
    if they don't wish to support per-function subtargets as would
    be needed for function multiversioning or LTO of disparate
    cpu subarchitecture types, e.g.
    
    clang -msse4.2 -c foo.c -emit-llvm -o foo.bc
    clang -c bar.c -emit-llvm -o bar.bc
    llvm-link foo.bc bar.bc -o baz.bc
    llc baz.bc
    
    and get appropriate code for what the command lines requested.

I found a patch by archlinux developer here :

http://pkgbuild.com/~lcarlier/mesa-git/sources/mesa-git/radeonsi.patch

It allows building mesa-git against latest llvm .

Works fine on NI/Turks XT, here.
Could be closed for my side.

Thanks Tom!
