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.
