Issue #26 (libatomic_ops).
Due to a misspelling in GCC, the check for the ARMv6KZ platform
uses ARM_ARCH_6ZK macro instead of ARM_ARCH_6KZ.
* src/atomic_ops/sysdeps/gcc/arm.h (AO_ARM_HAVE_DMB): Do not define
if __ARM_ARCH_6KZ__.
# if !defined(__ARM_ARCH_6__) && !defined(__ARM_ARCH_6J__) \
&& !defined(__ARM_ARCH_6T2__) && !defined(__ARM_ARCH_6Z__) \
&& !defined(__ARM_ARCH_6ZT2__)
-# if !defined(__ARM_ARCH_6K__) && !defined(__ARM_ARCH_6ZK__)
+# if !defined(__ARM_ARCH_6K__) && !defined(__ARM_ARCH_6KZ__) \
+ && !defined(__ARM_ARCH_6ZK__)
/* DMB is present in ARMv6M and ARMv7+. */
# define AO_ARM_HAVE_DMB
