Unix build errors #7665
Description
After getting the latest source, the Unix build fails (others e.g. Pyboard D still work).
$ cd ports/unix/
[adminpete@capybara]: /mnt/qnap2/data/Projects/MicroPython/micropython/ports/unix
$ make -j8
Use make V=1 or set BUILD_VERBOSE in your environment to increase build verbosity.

Followed by further messages with the same complaint. There is no extmod/crypto-algorithms/ directory on my clone, although there is a file extmod/extmod.cmake - this doesn't seem to point to such a directory.
