File 0050-S390-Add-configure-check-to-detect-support-for-arch1.patch of Package glibc-testsuite.13892

2019-03-22  Stefan Liebler  <stli@linux.ibm.com>

* config.h.in (HAVE_S390_MIN_ARCH13_ZARCH_ASM_SUPPORT,
	HAVE_S390_ARCH13_ASM_SUPPORT): New undefine.
	* sysdeps/s390/configure.ac: Add checks for arch13 support.
	* sysdeps/s390/configure: Regenerated.
