[PATCH] D77184: Make it possible for lit.site.cfg to contain relative paths, and use it for llvm and clang

[Richard Smith - zygoloid via Phabricator via llvm-commits]

rsmith added a comment.

This has broken my ability to run the `check-clang` target on Linux. There are symlinks in the path from which I run my builds, and this patch is computing incorrect relative paths in that situation.
