+This is a handy script, list of sources, and a MUSL git diff
+that can compile a significant number of functions in MUSL
+for freestanding use like mentioned before. You have to define some
+functions like \_\_errno\_location and strerror, but it's
+otherwise mostly functional and painless. Before you run
+the script inside the repository, you apply musl.git.diff
+to prepare the sources for such a compilation
