Numeric speed is not the reason to use maxima; there are many other
things that would be better suited.
I have not heard any one complain about the lapack routines in maxima
being too slow. In fact, I'm not sure any even uses them for anything. :-)
And one thing that we can do with the Lisp translation is massage it
relatively easily to do a bigfloat implementation. (I haven't actually
done this, but I did hack something to support quad-doubles. That
appeared to work for the couple of simple tests I tried.) Perhaps
there's already an mpfr version of lapack.

Last time I tried to build ATLAS was not exactly trivial, and took the
better part of a day. Perhaps it's better now.
