"linux" is the name of the component. It looks like opal/mca/timer/

on linux).
The timer components are a little different than normal MCA
frameworks; they *must* be compiled in libopen-pal statically, and
there will only be one of them built.
In this case, I'm guessing that linux was built simply because nothing
else was selected to be built, but then its component_open() function
failed because it didn't find /proc/cpuinfo.
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.
