fpcls on arm.

[Stagiaire Baptiste et Sandrine]

Hi,

I'm working on a D crosscompiler targetting arm cellphone running wince and 
I get some trouble with the compilation of the phobos library. It cannot find
the module gcc.config.fpcls.

In the configure script of phobos it appears that for some target the variable
d_use_ieee_fpsb is set. What does fpsb stand for and can we add arm on the list
of supported cpu ?
