S390: Add configure check to detect z13 as mininum architecture level set.
Add a configure check for z13 in the same way as done for z196. ChangeLog: * config.h.in (HAVE_S390_MIN_Z13_ZARCH_ASM_SUPPORT): New undefine. * sysdeps/s390/configure.ac: Add check for z13 support. * sysdeps/s390/configure: Regenerated.
