I'm cross compiling the tools for the ARM. Doing make in the top level
directory didn't work at first. I changed -I../include to -Iinclude in
tools/Module.mk and then it built fine with no errors.

I had to change the name of my i2c device name from /dev/i2c0 to
/dev/i2c-0 as the former was not recognized by the tools. We are using
a root filesystem created by OpenEmbedded, though I'm not sure who, or
what was responsible for the i2c device name :-).

The tools seem to work correctly after I renamed the device. It
correctly detected all the i2c devices on one of our boards.
