toolchain.eclass: mangle -O3 down to -O2, not -O0

In bug #701786 'strip-flags' removed all unsafe options
first including -O3 and only then mangled -O? to -O2.

This effectively made gcc to compalie wth -O0, generated
huge slow profile and confused LTO.

Let's default to safer -O3->-O2 transition.
