perf tools: Fix building error for arm64.

Commit b11db6581beaccef8ae9a388ae96074aa5cc144f ("perf tools: Fix build
error on ARCH=i386/x86_64/sparc64") uses sed on 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 prevent 'arm64' to be mached for 'arm.*' case.
