We're going to need this, and the PRINTF_FMT(1,2) in front of it caused
mockup.sh to miss the declaration.
We also eliminate the obviously-unused fallback case (which referred
to daemon/*.h).

update-mocks was broken, since it assumed the daemon/ directory.
We now use "make" directly to build the test file and harvest errors,
and are more robust if it simply doesn't compile (ie. fails, but no
linker errors).
