this from looking at code generated by gcc.

ee9003796a Fix fabs(). This commit brought to you by the letter 'l'.
(fstp stores a mem32 value, fstpl stores a mem64 value)

This fixes ghostscript for 'make release' on amd64.  Ghostscript for some
reason thinks it is a good idea to use -fno-builtin, which means it is
vulnerable to bugs in libc that are normally hidden by the builtin gcc
functions.  Oops.

AMD64 does away with the x87 in 64-bit long mode, so we have to play the
SSE/SSE2 game now.
