[wwwdocs] SPARC changes in 4.0

Again on the heels of MIPS (I borrowed the whole structure of mips-abi.html 
for sparc-abi.html in 3.4 :-), I've commited the patch below to describe the 
SPARC-specific changes in 4.0.  Not to say that they are of the same scope 
as those of MIPS of course...

Corrections and comments welcome too.
