[GIT PULL] Fix mcelog regression

[GIT PULL] Fix mcelog regression

[Luck, Tony]

Sorry for bypassing normal channels, but this looks like a trivial
regression fix to me, but I'm getting pushback from my co-maintainer
and from Ingo.

  1. This used to work
  2. Now it doesn't
  3. People have complained

So this fix is perfectly OK to me. The primary thing I 
objected to (which objection you did not quote!!), was the 
initial approach, the ugly vendor-specific switch you 
added:

The latest replacement commit you added looks clean - and 
/dev/mcelog is certainly a legacy we have to keep.

Thanks,
