This wasn't implemented correctly anyways, as it would need to recursively
rename directories that may not exist. Things would also get a bit
complicated if only some files in a directory were renamed.
Doable, but not needed for our use case.
For now just ignore any directory components. Though this may be worth
changing if the source directory structure becomes more complicated in
the future (maybe with a -r/--recursive flag?).
- Changed --(tool)-tool to --(tool)-path in scripts, this seems to be
a more common name for this sort of flag.
- Changed BUILDDIR to not have implicit slash, makes Makefile internals
a bit more readable.
- Fixed some outdated names hidden in less-often used ifdefs.
Added a couple flags to make the script a bit more flexible, and removed
littlefs-specific default in line with the other scripts which aren't
really littlefs-specific. (These defaults can be moved to the
littlefs-specific Makefile easily enough).
The original behavior can be reproduced like so:
./script/changeprefix.py lfs lfs2 --git
