Yes.  I've imported a new version of the SoftFloat package that arm32
uses, and tried to make it more amenable to use by other ports.  It lives
in src/lib/libc/softfloat and src/lib/libc/arch/${MACHINE_ARCH}/softfloat.  
Currently, the only port using it is arm26, but I think I've got the
portability hacks right.  If I haven't, please tell me rather than putting
yet another copy of SoftFloat in the tree.

I'm not reading tech-embed, but feel free to get in touch directly if you
want to talk about SoftFloat stuff.
