include: Disable compile time boundary check

Newer version of gcc keeps the calls to __write_overflow which is only a
compile time check. __write_overflow is implemented as error function
and as a result all the string functions fail with the overflow error.
Work around the gcc issue by defining the overflow functions as no-op.
