Details:

Hi, as lined out in

http://lists.gnu.org/archive/html/avr-libc-dev/2017-06/msg00000.html

this patch adds multilib support for the 2 new variants needed for avrxmega3
familiy (like ATtiny816).  No devices are added.  Without this patch, the
tools will generate wrong code because non-existing multilibs will silently
use default variant (avr2).

The according Binutils feature is here:
https://sourceware.org/PR21472

The according GCC feature is here:
https://gcc.gnu.org/PR81072



        Add multilib support for avrxmega3 + avrxmega3/short-calls.

        * configure.ac (CHECK_AVR_DEVICE): Add one for avrxmega3.
        (AM_CONDITIONAL): Add one for HAS_avrxmega3.
        (AC_CONFIG_FILES): Add avr/lib/avrxmega3/Makefile,
        avr/lib/avrxmega3/short-calls/Makefile.

        * devtools/gen-avr-lib-tree.sh (CFLAGS_SHORT_CALLS): New.
        (AVRXMEGA3_DEV_INFO): New.
        (AVRXMEGA3SC_DEV_INFO): New.
        (AVR_ARH_INFO): Add entries avrxmega3, avrxmega3/short-calls.

        * include/avr/pgmspace.h (__AVR_HAVE_RAMPD__): Fix comment.
