something like

floatformat_from_doublest()
{
#if HAVE_LONG_DOUBLE
  return floatformat_from_long_double (...)
#else
  return floatformat_from_double (...)
}

Yes, that would keep GDB insulated from liberty's configuration internals.

(Any long term signs of a portable target floating point library (so 
that the code can completly avoid host fpu assumptions?).  glibc's 
floating-point code has been suggested in the past.)
