fix

All the suspicious flags reviewed and looked OK excepted maybe
-maccumulate-outgoing-args that looks safer when initialized from the .opt
files, and overridden only in case of conflict with unwind tables.

Removed entirely the forcing of -fomit-frame-pointer as we discussed, since it
doesn't seem needed anymore. However, note that if we shall discover that it is
still in use for a non dwarf2 target, the line should be moved to
common/config/sh:sh_option_init_struct()

checked that omit-frame-pointer is correctly enforced for -pg from
sh_frame_pointer_required.

I'd like to push it to the 4.6, 4.7, validated under sh-superh-elf. 
sh4-linux on-going.

Thanks
