two libgcc.so thoughts

[Richard Henderson]

(1) I think I'm with Zack in wanting to move the C++ bits out
    of libgcc.  If you want to put them in another language
    support library besides libstdc++, I can do that.  But I
    think it's a mistake to leave them where they are.

(2) In thinking about how to pre-process symbol version scripts,
    I can't think how to do them in sed or some such, expecially
    with the broken seds that we cater to.  Perl or awk would be
    fairly easy.  It's probable that it could be done in sh, but
    it would be damned ugly.

    We don't currently require awk in the build process.  Does
    this seem like an unreasonable requirement in order to build
    the shared libgcc?
