Juan Carrano	547d9f0802	makefiles/utils: Add a function for checking that a string is not empty. ... A call to `$(ensure_value x,y)` will fail with message y if x is empty, and otherwise return x. This can be useto write more compact makefiles, while still producing friendly error messages.	2018-12-07 18:19:34 +01:00
