ftrace: handle generic arch calls
The recordmcount script requires that the actual arch is passed in. This works well when ARCH=i386 or ARCH=x86_64 but does not handle the case of ARCH=x86. This patch adds a parameter to the function to pass in the number of bits of the architecture. So that it can determine if x86 should be run for x86_64 or i386 archs.
