[net.arch] FPUs for 16k vs 68k vs 432 vs x86

Must not be quite so impossible to put an 8087 on a 68000 (at least if you
have the resources of an IBM) since their new XT370 uses custom
microprogrammed versions of two 68000s and an 8087 to implement the 370
instruction set (I suppose they also had a few gates of interface logic bent
to their speicifications too).

I believe that Jeff Arnold (mit-vax!jma) interfaced an 8087 to a 68000
for his Bachelor's Thesis projects, so it doesn't require huge
resources.  I don't recall what sort of hacks were required though.
