Removing the #undef gives a diff for param.arm_linux26.h of,

--- openafs-1.6.9/src/config/param.arm_linux26.h
+++ openafs-1.6.9/src/config/param.arm_linux26.h

-/* glibc doesn't implement getcontext/savecontext for arm. */
-#undef USE_UCONTEXT

  #endif /* AFS_PARAM_H */

which when trying to build the package unfortunately still ends up with 
the same error,
