Yann, All,

I cannot judge what it really means coupling all these libraries with this option.
I can only see that unchecking TARGET_ENABLE_OPTSPACE is currently required
for this particular arch+compiler, compiling the rest with -Os is maybe OK.

I would like to keep that patch as is and not mix it with further changes,
also because a new "global" option could require a test marathon that I cannot conduct.
And reducing the number of these options can been done at any time afterwards.

Regards
Titus
