Bug#626129: perl: sh4: FTBFS: Failed at op/ver.t line 241

tags 626129 patch
thanks

Hi,

I made the patch which changed the optimization level of utf8.c from O2 to O1.
I understand that it is not right solutuon, I need to revise gcc.
Would you apply this patch until gcc is revised?

Best regards,
  Nobuhiro
