Oops.  I had stopped too early in looking up the earlier discussion of this 
problem.

   Both /usr/local/include/urcu/config.h and 
/usr/src/userspace-rcu-0.8.0/urcu/config.h have '#define 
CONFIG_RCU_ARM_HAVE_DMB 1' and commenting this out may allow the makes to 
complete.

   I have no idea how this 'arm-angstrom-linux-gnueabi' relates to armv4 
user-space vs. armv7 kernel space.

   Jon, could you elaborate on the --build and --host fix?
