Do you need to spawn two shells? It seems like:

  $(shell expr `expr "$(uname_R)" : '\([0-9][0-9]*\)'` '>=' 11),1)

Oops, I missed the trailing '.' in the regex there, and it probably
needs double-quotes in case the inner expr fails to match anything.

We could also use "test -gt" instead of the outer expr, which is more
idiomatic shell. But it reports via exit code, so you'd need "&& echo 1"
at the end.
