This is actually incorrect. The linux component looks for /proc/
cpuinfo and builds if it founds that file. There's a base component
that's built if nothing else is found. The configure logic for the
linux component is probably not the right thing to do -- it should
probably be modified to check both for that file (there are systems
that call themselves "linux" but don't have a /proc/cpuinfo) is
readable and that we're actually on Linux.
