Subject: [feature/native-comp] out-of-tree build process broken
Date: Mon, 17 Aug 2020 08:16:26 -0700

When feature/native-comp branch is built out-of-tree, emacs cannot find the .eln files during start.

The patch below fixes this issue. The problem is caused by the fact that during an out-of-tree build, default-directory points inside the build tree while the .eln files are found in the source tree and because of that the subsequent replace-regexp-in-string fails to adjust the file path of the compilation unit.
