arm: rmobile: Support build with gcc-4.6 or later
Latest rmobile code was tested by using old gcc (gcc-4.4). When we use gcc-4.6 (or later), the build is made, but does not work. This solves a problem not to work by add -march=armv5 to compiple option when we built in gcc-4.6 (or later). I tested by linaro's compiler version 2012.04-20120426.
