The existing norm for architectures is that without any parameters, it
will work for ~all machines. If someone wants optimized defaults, they
have the option of passing a flag during builds.
Similarly, i386 compilers will build i486 code, and not assume SSE
That one is probably least likely to be done. I am including it for the
sake of completeness.
It's mostly the decision of the hppa portmaster, but if he doesn't
respond in some amount of time I'll ask to leave things as is. It
already works for us, and should be fine.
We can change both upstream and our local GCC copy if we want to
