Bug#730505: ioapps: FTBFS on everything except I*tel like architectures

[Roland Stigge]

Package: ioapps
Version: 1.4r2-3
Severity: important
Tags: patch
User: debian-powerpc...@breakpoint.cc
Usertags: powerpcspe

Hi,

since ioapps uses the rdtsc assembler instruction it fails to build from source
on all architectures except I*tel.

Attaching a patch that fixes the issue on powerpc.
