Hi,
While trying to build the examples with a fresh pull from upstream,
I got the following build error from gccdeps:

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.
I struggled with this stuff also in the new build system. waf is pretty
nice, once you figured out how something works, but at least for me it
was always very hard to figure out solutions. I can write Makefiles a
hundred times faster. Maybe this helps:
