[PATCH] S390: Fix build error in iconvdata/bug-iconv11.c

[Stefan Liebler <stli at linux dot vnet dot ibm dot com>]

Hi,

I get the following build error on S390 31bit while building the test 
iconvdata/bug-iconv11.c with gcc 5.3:

bug-iconv11.c: In function âtest_ibm93xâ:
bug-iconv11.c:59:11: error: format â%tdâ expects argument of type 
âptrdiff_tâ, but argument 2 has type âsize_t {aka long unsigned int}â 
[-Werror=format=]
   printf ("  ==> %td: %s\n"
           ^
cc1: all warnings being treated as errors

This patch uses %zu format specifier for argument size_t ret instead of %td.

Ok to commit?

Bye
Stefan

ChangeLog:

	* iconvdata/bug-iconv11.c (test_ibm93x):
	Use %zu printf format specifier for size_t argument.
