glibc has not been ported to any EBCDIC target, and I doubt it ever
will be ported to an operating systems that's primarily EBCDIC-based.

The implementation is expected to output the character '4' for the
number.  The mechanism used for that is not specified.

In practice, I expect it will eventually converted to ASCII or UTF-8
these days because native EBCDIC terminals are extinct.  But on an
EBCDIC system, the program itself will write EBCDIC, it just gets
translated later.

That depends a lot on on the operating system and the file system.
That's not really specific to EBCDIC, it's a fairly complex topic
everywhere (even on Linux, despite its generially lenient pathname
syntax).
