[PATCH -tip] perf tools: fix building error for arm64.

From: Wang Nan
Date: Tue Mar 17 2015 - 07:51:11 EST


Commit b11db6581beaccef8ae9a388ae96074aa5cc144f ("perf tools: Fix build
error on ARCH=i386/x86_64/sparc64") use sed process ARCH, which triggers
a bug in sequence of sed expression, where 's/arm.*/arm/' will replace
'arm64' to 'arm', causes arm64 building failure.

This patch replaces 'arm64' to 'aarch64' before 's/arm.*/arm/' to
protect arm64 and replaces 'aarch64' back to 'arm64' after fixing
'arm.*'.
