Because fbcc is the same as fbcc.w, just like bcc is the same as bcc.w.
For the latter there is the notation of jbcc in the MOTOROLA case, but
there is no equivalent notation for fpu branches, at lease gas does not
recognise it, maybe it should? (There is no fbcc.s, btw, the fpu branches
only come with 16 or 32 bit offsets).
