I will remove it, but first I'd like to make a few other checks:

I had a look to see why this was broken since the 4.6, and it appears that the
line was well formed when it lived within the OPTIMIZATION_OPTION hook. However
it was removed and all the settings moved away first to the
TARGET_OPTION_OVERRIDE hook, which now is bogus.

in the 4.6 branch we could still use TARGET_OPTION_INIT_STRUCT but not in the
4.7. so the fix will certainly differ between branches.

So I'd prefer that all the internal variables that used to be set in
sh_optimization_option should be double checked.
