Hi,
avr-rtems uses _exit from newlib and therefore filter out _exit from
LIB1ASMFUNCS.
I intend to commit the patch below, which is supposed to be a port of
what RTEMS had used in gcc/config/avr/t-rtems in gcc < 4.7.

* config.host (avr-*-rtems*): Add config/avr/t-rtems.
* config/avr/t-rtems: New.
Filter out _exit from LIB1ASMFUNCS.
