No, it was me.  I consistently measured ~2% speed difference in `make build'
time when I tried this about the time we moved from a static to a shared
libgcc.  I hesitate to say it was done under strictly controlled conditions,
but it was certainly reproducible.  I would be somewhat surprised if it were
actually as high as 15%, though.  I'm looking forward to seeing Todd's
numbers, especially with the current toolchain.

My objection during the last discussion was that since it was consistent and
measurable, we need to think long and hard before committing to this path.
It's easy to write off several 1% and 2% penalties before we realize that
we're `suddenly' 10% slower than we were a year ago.
