[PATCH, FRV, libgcc]: Move CRT_GET_RFIB_DATA to libgcc

[Uros Bizjak]

Hello!

Attached patch moves CRT_GET_RFIB_DATA from gcc to libgcc in the same
way as was recently done for x86 targets [1].

The second patch is needed to successfully compile frv-elf libgcc,
otherwise libgcc build fails in defaults.h, line 499 with "Unknown
BITS_PER_UNIT" error.

libgcc/ChangeLog:

2015-04-22  Uros Bizjak  <ubizjak@gmail.com>

    * config/frv/elf-lib.h: New file.
    (CRT_GET_RFIB_DATA): Move definition from gcc/config/frv/frv.h.
    * libgcc/config.host (frv-*elf, frv-*-*linux*): Add frv/elf-lib.h
    to tm_file.

2015-04-22  Uros Bizjak  <ubizjak@gmail.com>

    * config/frv/frvbengin.c: Do not include defaults.h
    * config/frv/frvend.c: Ditto.

gcc/ChangeLog:

2015-04-22  Uros Bizjak  <ubizjak@gmail.com>

    * config/frv/frv.h (CRT_GET_RFIB_DATA): Move definition to
    libgcc/config/frv/elf-lib.h.

Patch was tested by building frv-elf crosscompiler and multilib.

OK for mainline?
