S390: Fix build failure in test string/tst-endian.c with gcc 6.
Building string/tst-endian.c with gcc 6 produces an build warning/error on s390 (big endian machine): gcc tst-endian.c -c -std=gnu11 -fgnu89-inline -O2 or -O3 ... tst-endian.c: In function ‘do_test’: tst-endian.c:16:30: error: self-comparison always evaluates to false [-Werror=tautological-compare] if (htobe16 (be16toh (i)) != i) ^~ ... See definitions of htobexx, bexxtoh in string/endian.h: ... This patch silences these warnings with DIAG_* macros if build with gcc 6 and newer. The same warnings occur on little endian machines with the "htoleXX (leXXtoh (i)) != i" if-statements. ChangeLog: * string/tst-endian.c: Include <libc-internal.h>. (do_test): Ignore tautological-compare warnings around "htobeXX (beXXtoh (i)) != i" and "htoleXX (leXXtoh (i)) != i" if-statements.
