commit b8686c0d7098168481a246f8199ab2d865f52d3d
Author: Stefan Liebler <stli@linux.ibm.com>
Date: Tue Dec 18 13:57:03 2018 +0100
S390: Add configure check to detect z10 as mininum architecture level set.
Add a configure check for z10 in the same way as done for z196.
ChangeLog:
* config.h.in (HAVE_S390_MIN_Z10_ZARCH_ASM_SUPPORT): New undefine.
* sysdeps/s390/configure.ac: Add check for z10 support.
* sysdeps/s390/configure: Regenerated.
