stdio-common: Add scanf integer data for ILP32 targets

Add Makefile infrastructure and `int' and `long' integer input data,
signed and unsigned, for ILP32 targets.

While the size of `int' data is the same between ILP32 and LP64 targets,
resulting scanf output is different between them for out of range input
data and while ISO C and POSIX both say that the behavior is undefined
if the result of the conversion cannot be represented we want to keep
track of our output to prevent inadvertent changes.  Hence the use of
distinct `int' integer input data between ILP32 and LP64 targets.

Keep input data disabled and referring to BZ #12701 for entries that are
are currently incorrectly accepted as valid data, such as '0b' or '0x'.
