mprintf: check fputc error rather than matching returned character

Browse source 
OS/400 ascii fputc wrapper deviates from the posix standard by the
fact that it returns the ebcdic encoding of the original ascii
character. Testing for a matching value for success will then always
fail.

This commit replaces the chariacter comparison by an explicit error
return check.
