The list of supported platforms is *definitely* too small for LLVM users.
Half of their support is "best effort", which really isn't going to cut it
once we forcefully depend on it.

We definitely run benchmarks on X86_64, Arm32/64, MIPS, PowerPC (Linux, Mac
and Windows on a mix of those), and there are probably people running on
SystemZ, RISCV and other less known architectures.

What is your plan for all the other platforms where abseil isn't supported?
