Probably not a horrible idea; but we should see how big the patch is
first, and how much maintenance all the #ifdefs would be, versus the two
lines in dmesg that might annoy.  Perhaps we should spend the time on a
way to ignore command failures instead and tell the function that checks
for mesh capability to be silent or print out a more informative message
that doesn't look so scary.
