Another similar thing to consider is for people building LLVM within
Python extensions (llvmlite, dragonffi, cppyy and others!). Python
wheels under Linux are built using a fixed CentOS version. A new ABI
(manylinux2010) appeared recently
(https://www.python.org/dev/peps/pep-0571/) that uses CentOS 6. I don't
know which C++ library is used here, but if it is too old, it could also
be an issue !

My 2 cents.
