Details:

For the past several weeks building off master has resulted in errors when
using 4 parallel jobs however building without parallel is fine.

This week's errors introduce themselves around the generation of header files
(prepending "DO NOT EDIT"), and it's not always the same header file.

>From `make -j4 -w all html` on commit `37f29c`:


rm -f unilbrk.h-t unilbrk.h && \
        { echo '/* DO NOT EDIT! GENERATED AUTOMATICALLY! */'; \
