[PATCH] D112082: [libunwind] Use the from-scratch testing configuration by default

[Petr Hosek via Phabricator via llvm-commits]

phosek added a comment.

I think this may have broken our builders since all libunwind tests now fail with the same error:

The `/b/s/w/ir/x/w/staging/llvm_build/runtimes/runtimes-x86_64-unknown-linux-gnu-bins/lib/libunwind.a` is invalid, in the bootstrapping build it should be `/b/s/w/ir/x/w/staging/llvm_build/lib/x86_64-unknown-linux-gnu/libunwind.a`.
