ROOT 6.24 breaks Alice O2 due to symbol confusion with system llvm 11 #8180
Description
Compile Alice O2 with ROOT 6.24 and run a simulation, but I get crashes which apparently come due to symbol confusion with my system llvm 11. Here is a stack trace:

This is on 64 bit Gentoo Linux compiling ROOT myself with GCC 10.2.
I assume the llvm11 is pulled in by libgandiva of apache-arrow, which links to my system llvm.
I do not see this problem with ROOT 6.22.08 (setup identical otherwise), so I assume it might be to the bump of the LLVM version in ROOT.
So far I have tried the 6.24.00 tag and the v6-24-00-patches branch, both with the same result.
For reference, we had very similar issues quite a while ago, which was fixed by #4689, although perhaps now it is the other way around, with ROOT linking to my llvm11 symbols.
