Subject: [PATCH] Do the targetarch dependency stuff better.

SConscript:
    targetarch is only for headers, not cc files.  move all cc files
    back to arch/alpha, and make the target arch directory do this
    echo '#include "arch/alpha/foo.hh"' > targetarch/foo.hh for every
    header file.  This works a lot better and doesn't kill emacs'
    ability to parse compile outputs
