[patch] System call for multi-architecture

[Yao Qi <qiyaoltc at cn dot ibm dot com>]

There were two threads in this maillist about this issue, and I
modified this patch for several time per Mark and Tom's comments, and
feedback from these two threads.

This patch could provide,
  1) draft system call list(for x86, x86_64, and powerpc).
  2) ftrace could work on these three platforms.

This patch could not provide, or could provide in the next step,
  1) 64-bit ftrace trace 32-bit app.
  2) accurate arguments for some system calls.

Mark, Sami,
the patch could give you syscallLists for different architecture.
