Arnaud, All,

If you set an optimisation level in the crosstool-NG configuration, it
will only be used internally, for example to build libstdc++ or libgcc_s.

There is no way to tell gcc what optimisation level to default to. So,
you have to specify the required optimisation level everytime you call
to gcc.
