[patch committed] Fix SH bootstrap failure

Hi,

I've applied the attached patch to fix bootstrap on SH. Currently
it fails with

cc1: internal compiler error: in cl_optimization_save, at options.c:5572

during building target libgcc.
cl_optimize_save checks if flag_omit_frame_pointer is in the range
0-255 but SH may set it to -1 temporarily at OPTIMIZATION_OPTIONS.
Although OVERRIDE_OPTIONS will reset its value to zero, it seems that
cl_optimize_save checks the value before OVERRIDE_OPTIONS runs.

Regards,
    kaz

    * config/sh/sh.h (OPTIMIZATION_OPTIONS): Set flag_omit_frame_pointer
    to 2 instead of -1.
    (OVERRIDE_OPTIONS): Check if flag_omit_frame_pointer is equal
    to 2.
