elfos.h (ASM_OUTPUT_LABELREF): Don't define.

* config/elfos.h (ASM_OUTPUT_LABELREF): Don't define.  The default
is right for most ELF targets.
* config/ns32k/ns32k.h (ASM_OUTPUT_LABELREF): Don't define.
Let the default file use %U properly.
* config/sh/elf.h (ASM_OUTPUT_LABELREF): Don't define.  Use the
default.

* config/fp-bit.c (pack_d): Properly handle rounding of denormal
numbers.
