so that a Windows-friendly .lib can easily be built when using --shared.
Updated install directions to reflect this and give guidance. If you need
.lib atlas files under Windows, everything except one line of typing (given in
install guide) should all be automatic now.
The ARM/HARDFP patch at least didn't break my SOFTFP-ABI machine, so I
am still hoping to release 3.10.0 tomorrow.
ATLAS 3.9.87 released 07/09/12, changes from 3.9.86:
* Updated atlas_install to discuss dll build & ARM/HARDFP
* Modified Windows dll build to generate .def files for LIB usage
