Hi,

(Readding Hans to CC, who asked to be kept in the loop - I missed that on 
the previous mail, sorry)

Also it seems like this buildbot runs just fine on later commits. When 
checking the adjacent builds:
http://lab.llvm.org:8011/builders/clang-x86_64-linux-abi-test/builds/14087
http://lab.llvm.org:8011/builders/clang-x86_64-linux-abi-test/builds/14088
http://lab.llvm.org:8011/builders/clang-x86_64-linux-abi-test/builds/14089
http://lab.llvm.org:8011/builders/clang-x86_64-linux-abi-test/builds/14090
http://lab.llvm.org:8011/builders/clang-x86_64-linux-abi-test/builds/14091

These builds built the following SVN revisions:
build - SVN rev
14087 - 310988 - all ok, prior to my commit
14088 - 310990 - broken on my commit
14089 - 310991 - failed (310991 in llvm requires 310992 in lld, which was 
committed 11 seconds after 310991)
14090 - 310989 - built an older revision again, all ok
14091 - 310994 - newer rev, also ok

There were no other changes in the LLVM tree between revs 310991 and 
310994 (the next one there was 310996), so I would conclude that this was 
a stray failure, unrelated to my commits - do you agree?
