I think a more "automatic" solution to catch those errors is to try to build
with -Wundef. For libosmocore, there is currently some fall-out with EMBEDDED (we'd have to explicitly #define EMBEDDED 0 via autoconf).
The advantage of the -Wundef approach is that it should work for all such
'forgot to include a header defining a macro' use cases, and it doesn't require
an external tool for validation. Just add -Wundef to our normal build flags.
