ftrace: create default variables for archs in recordmcount.pl

Impact: cleanup of recordmcount.pl

Now that more architectures are being ported to the MCOUNT_RECORD
method, there is no reason to have each declare their own arch
specific variable if most of them share the same value. This patch
creates a set of default values for the arch specific variables
based off of i386.
