[PATCH] bsp/leon3: Use -mcpu=leon3 GCC option

[Sebastian Huber]

There is support for the LEON3 processor available in Binutils 2.24 and
the GCC 4.8 branch and GCC mainline.

GCC 4.8 branch:

http://gcc.gnu.org/viewcvs/gcc/branches/?view=log&pathrev=205331

GCC mainline:

http://gcc.gnu.org/viewcvs/gcc/trunk/?view=log&pathrev=202664

This is critical for further SMP development on LEON3 since it enables
usage of C11 atomic operations.  It makes it also possible to use an
inline function for _CPU_SMP_Get_current_processor() which avoids the
function call overhead in critical sections.
