configure: silence preprocessor noise from dependency generation 

Currently, errors are thrown for various macros while building that are completely bogus.
They occur during the dependency (.d) generation phase, and have no bearing on the compiled output,
since only the stdout is piped into the sed command to generate the .d files.
They basically occur as the relevant -I paths are not (and cannot be passed) during
the dependancy generation phase.
As such, this patch silences them.
