[PATCH] D134454: [Driver][Distro] Fix ArchLinux sysroot detection

[Fangrui Song via Phabricator via cfe-commits]

MaskRay requested changes to this revision.
MaskRay added a comment.
This revision now requires changes to proceed.

I'll grab an Arch Linux machine for testing, but I don't think this is currently in a form for submitting.
This adds new functionality for non-MIPS and we need some fake file hierarchies (like those used in `linux-cross.cpp`).
I'll add the test, though.

Request changes for now.
