relocation R_X86_64_PC32 against symbol `_ZTVN4llvm11raw_ostreamE@@LLVM_7' can not be used

Hi, trying to build llvmlite 0.27.1rc1 this build break came up:

One workaround to do this is to compile llvmlite by forcing the usage of -fPIC:

CXX="g++ -fPIC" pip install llvmlite

You might not see this on Ubuntu machines because -fPIC and -pie are set by default (https://wiki.ubuntu.com/SecurityTeam/PIE).

I guess this needs to be fixed in llvmlite’s setup.py somehow!

I am getting a similar error again using llvmdev from the numba channel:
