Log message:
Add News info of 4.7.3 to 4.8.3 part to COMMIT_MSG

Log message:
Correction (Removing) the harmful line (if ${AVR_TARGET} is empty), as
-BUILDLINK_FNAME_TRANSFORM.avr-gcc+=    -e "s,${AVR_TARGET}/lib/,lib/,g"
(with comment, getting .builkdlink/lib/ -> .buildlinklib/ )

Looking for the resolution for packaging emulators/simulavr and
wip/simulavr-git (former has another problem now).

Log message:
libiberty.a is required by simulavr. Move it to more visible PATH from simulavr.

Log message:
Update avr-gcc 4.7.3 to 4.8.3
- libiberty.a will be installed as
    lib/gcc/avr/${PKGVERSION}/libiberty.a
  (previous 4.5.3, and 4.7.3 did not have the one).
  and it is moved from lib/libiberty.a to above to avoid confilct to
  other cross and native tools.

>From grepping 'avr' from NEWS file:
---------------------------------
   On AVR, the configure option --with-avrlibc supported since GCC 4.7.2
   is turned on per default for all non-RTEMS configurations. This option
   arranges for a better integration of [3]AVR Libc with avr-gcc. For
   technical details, see [4]PR54461. To turn off the option in non-RTEMS
   configurations, use --with-avrlibc=no. If the compiler is configured
   for RTEMS, the option is always turned off.

     * Support has been added for the AVR-specific configure option
       --with-avrlibc=yes in order to arrange for better integration of
       [3]AVR-Libc. This configure option is supported in avr-gcc 4.7.2
       and newer and will only take effect in non-RTEMS configurations. If
       avr-gcc is configured for RTEMS, the option will be ignored which
       is the same as specifying --with-avrlibc=no. See [4]PR54461 for
       more technical details.
