`file src/MMU_timing.h` in the build directory suggests that the header
file is shipped with CRLF line endings. Could `git format-patch` be
converting \r\n in your files into plain \n?

I tried to work around this with some combinations of
(origin (patch-flags '("--ignore-whitespace" "-p1"))), but no results.
