Those are flags that need to be passed to the new gcc that you build,
when it is run to generate ARM/Maverick code. As far as ct-ng is
concerned, assuming you're building a usual cross-compiler, they would
need to be used while cross-compiling the C library that will be used
on the target system - that is the option you need to locate; it'll
probably be called LIBCFLAGS or something like that;
