    Restore buildworld from clang (adjust libm)
    
    Functions like "isinff" come from GCC only, causes a missed reference when
    the world is built with clang.  To solve, bring back FreeBSD versions of
    round(|f|l).  An additional benefit is that these functions appear to be
    improved over the OpenBSD versions (avoids unnecessary conversions).  The
    FreeBSD roundl uses ENTERI/RETURNI macros so I left these off meaning DF
    will still not able to raise exceptions on roundl.
    
    Since isinff and friends are no longer used, clang can continue further with
    building the world.
