Vincent Palatin 686a23585e optimize printf size without the common runtime ...

When a platform is built without the common runtime to optimize for
flash size, remove the 64-bit support in printf to save more space
(mainly by getting rid of the uint64divmod helper).

This saves 376 bytes of flash on Zinger/MiniMuffin.

BRANCH=none
BUG=none
TEST=make buildall and compare flash size with and without the change.
the common runtime binaries are identical excepted the version
information.
