linux-next: build failure after merge of the arm-current tree

[Stephen Rothwell]

Hi Russell,

After merging the arm-current tree, today's linux-next build
(lots of configs) failed like this:

/bin/sh: 1: arithmetic expression: expecting primary: " "
(lots of these)

Caused by commit

  fe680ca02c1e ("ARM: replace unnecessary perl with sed and the shell $(( )) operator")

(pointed out by Michael Ellerman)

Our /bin/sh is dash not bash ...

Cheers,
Stephen Rothwell
