[PATCH] m32r: enable asm code optimization
Add -O2 option to AFLAGS to enable asm code optimization for m32r.
On m32r gas, "-m32r2 -O" option enables assembler's parallel code
generation optimization for M32R2 ISA as a default. So, "-no-parallel"
option is required explicitly for a cpu core with single instuction
issuing, for example, VDEC2.
