Agreed.

I really don't think it's safe to add -D_FILE_OFFSET_BITS=64 to the
default CFLAGS.  Code will start getting bigger numbers and will
need to cope appropriately lest they overflow.   It'd be draconian
but I'd prefer to do something like was done for open() (I think?)
a while back and fail to link if the 64 bit interfaces aren't used.
That'd require each app/maintainer to do an audit and be thoughtful
about the fixes.
