Nope, no pre-stripping was done.  The first sizes I posted were the files as
they exist after "make install"; what make does to them during installation
I don't know.  The command sequence was as I posted.

.note has a defined structure, but a defined meaning.  We're free to add
things to the array.  (I have no idea what the syntax would be, and the gas
docs don't say.  A "gcc_options" entry in the .note array would probably be
the cleanest solution, but I don't know enough assembly pseudos to do that.
So I picked .comment instead.)
