S390: Add configure check to detect z10 as mininum architecture level set.

Browse Source 
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.
