H A DMakefilediff 6cea14f55474ec71f1098228e0ae5dd2a8f22c0a Mon Apr 16 14:21:54 CEST 2018 Russell King <rmk+kernel@armlinux.org.uk> ARM: replace unnecessary perl with sed and the shell $(( )) operator

You can build a kernel in a cross compiling environment that doesn't
have perl in the $PATH. Commit 429f7a062e3b broke that for 32 bit
ARM. Fix it.

As reported by Stephen Rothwell, it appears that the symbols can be
either part of the BSS section or absolute symbols depending on the
binutils version. When they're an absolute symbol, the $(( ))
operator errors out and the build fails. Fix this as well.
