    Ensure that we don't produce code for pre-ARMv7 without barriers · 9fe7d20e
    Ben Gamari authored and Ben Gamari's avatar Ben Gamari committed 
    We are unable to produce load/store barriers for pre-ARMv7 targets.
Phab:D894 added dummy cases to SMP.h for these barriers to prevent the
build from failing under the assumption that there are no SMP-capable
devices of this vintage. However, #10433 points out that it is more
correct to simply set NOSMP for such targets.
