LEON3: use new mcpu=leon3v7 build flag
The LEON3 BSP has been using mcpu=cypress which is a
SPARCV7 that is compatible with SPARCv8 CPUs. This patch
enables the relatively new LEON3 model and generates
SPARCv7 compatible code. This shuold be comptabile with
all single-core LEON3/4 systems. The LEON3 model is
required for SMP to make GCC generate the CAS instruction.
