[Minios-devel] [UNIKRAFT/NEWLIB PATCH] Configure IO C99 formats and errno extensions

[Costin Lupu <costin.lupu@xxxxxxxxx>]

This patch adds support for enabling the following extensions:
* IO C99 formats enable more options for formatting output. We need this to
support "%z" in Python 3
* Linux errno extensions define more error numbers. We need this to support
ESHUTDOWN in Python 3
