Can you point at which open bugs in that list actually affect packaging for
Debian? I assume http://llvm.org/pr15493, which is about building a
monolithic libLLVM-N.M.so, is the main one and nothing else matters.

When packaging, do you build all the LLVM subprojects together or
separately one after another? If you build separately, you should be able
to build compiler-rt with cmake and keep building LLVM with autoconf.
