integrated -save-temps and the death of specs

[Richard Kenner]

    i got very upset at specs files today and decided to start the painful
    process towards getting rid of them altogether.  

I think that would be a major step *backwards*.  The advantage of specs
file is that you can make changes to the way commands are called without
having to recompile anything.

I would much prefer to go in the direction of having *more* specs files
(for example language-specific) so that we become less depenendent on
the particular binary of the driver being used.  We have had lots of
problems with this in the past.
