Ah. Yes that is only required if printf is used. This requirement comes
from a libcdl issue: currently there is no way currently to express that if
CYGDAT_LIBC_STDIO_DEFAULT_CONSOLE is set to /dev/ttydiag or /dev/haldiag,
then you need to have those implemented in the I/O package. This came from
some point before when some user tried to do this (use /dev/ttydiag when
CYGPKG_IO_SERIAL_HALDIAG wasn't enabled). Since CYGPKG_IO_SERIAL_HALDIAG is
the default and most common case this requirement was added.

Maybe the requirement should not exist and I should assume that that user's
mistake was a one-off. Opinions?

Certainly you should be able to comment it out in your sources.
