[LTP] [RFC][PATCH] Add cpu architecrute check

[Nobuhiro Iwamatsu <iwamatsu.nobuhiro@renesas.com>]

Some system call test program depends cpu architecture.
We cannot compile these, and there is a case to fail in a test even if
We compile it.
This check cpu architecture and build check in Makefile.
This didn't check all syscall and test cases.
