[PATCH] D50246: [RISCV] Add support for computing sysroot for riscv32-unknown-elf

Thanks for reopening this @kristina.

I suggest passing `--sysroot=` to make sure we see the expected behaviour when the sysroot is actually empty.

Note that this would not really test the scenario where `DEFAULT_SYSROOT` is empty **and** no `--sysroot` appears in the command line. I'm not sure if we really want to test that case (but if we do, I think we will have to move that case into a test of its own and add a //feature// in `lit.cfg.py` that describes that clang does not have any built-in default sysroot).

Thoughts?
