s390x: Require GCC 7.1 or later to build glibc.
GCC 6.5 fails to correctly build ldconfig with recent ld.so.cache commits, e.g.: 785969a047ad2f23f758901c6816422573544453 elf: Implement a string table for ldconfig, with tail merging If glibc is build with gcc 6.5.0: __builtin_add_overflow is used in <glibc>/elf/stringtable.c:stringtable_finalize() which leads to ldconfig failing with "String table is too large". This is also recognizable in following tests: FAIL: elf/tst-glibc-hwcaps-cache FAIL: elf/tst-glibc-hwcaps-prepend-cache FAIL: elf/tst-ldconfig-X FAIL: elf/tst-ldconfig-bad-aux-cache FAIL: elf/tst-ldconfig-ld_so_conf-update FAIL: elf/tst-stringtable See gcc "Bug 98269 - gcc 6.5.0 __builtin_add_overflow() with small uint32_t values incorrectly detects overflow" (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=98269)
