It's doing an error check to find the build dependency fs-root-tar.h,
which gets generated in the build directory by bin2c. This has always
been tricky to handle in waf. I don't grok the way Chris reworked the
rootfs support in the example so I don't immediately see the root
(hah) problem or how to try to fix it.
