    libc: centralize a few numeric symbols
    
    fabs, __infinity, and __nan are universally implemented so declare them
    in gen/Symbol.map.
    
    We would also include __flt_rounds, but  it's under FBSD_1.3 on arm so
    until that's gone we're stuck with it.  Likewise, everyone but i386
    implements fp[gs]etmask.
