[PATCH] ftrace: update recordmount.pl arch changes

From: Steven Rostedt
Date: Fri Aug 15 2008 - 11:40:41 EST



Ingo,

I'm trying to keep all the arch changes in recordmcount.pl in one place.
I moved your code into that area, by adding the flags to the commands
that were passed in.

Does this change still work for you when compiling i386 on a x86_64 box?
