[PATCH] D154357: [Driver] Recognize powerpc-unknown-eabi as a bare-metal toolchain

[Fangrui Song via Phabricator via cfe-commits]

MaskRay added a comment.

The code change looks good but the driver test will cause an issue.
I think we need a fake sysroot tree under `Inputs/`.
Otherwise if we have a system cross gcc at `/usr/lib/gcc{,-cross}/powerpc64le-unknown-eabi/12`, Clang Driver will pick up these files.
This is really difficult to debug for someone not so familiar with Driver (I think I have done quite a lot of work, but still quite puzzled).
You may check many other tests using --sysroot, remove --sysroot, and check the behavior change.
