Hi there!

I just wanted to give a heads up that it looks like this patch is causing failures on some of the PPC bots that build with shared libraries:
https://lab.llvm.org/buildbot/#/builders/57
https://lab.llvm.org/buildbot/#/builders/121

The error looks like this in https://lab.llvm.org/buildbot/#/builders/121/builds/21343/steps/4/logs/stdio:

Are you able to look into this?

Thanks.
