Because of:
<http://sourceware.org/ml/gdb-patches/2013-08/msg00289.html> I have chosen to revert the patch applied to the AVR target-dependent code. Therefore, this patch does just that. It is better to keep the tree buildable than to keep this patch in, for now. 2013-08-12 Sergio Durigan Junior <sergiodj@redhat.com> Revert implementation of gdbarch_gdb_signal_{to,from}_target for AVR. * avr-tdep.c: Remove include of "linux-tdep.h". Remove enum with different signals between the generic Linux kernel implementation and AVR's. (avr_linux_gdb_signal_from_target): Delete. (avr_linux_gdb_signal_to_target): Delete. (avr_gdbarch_init): Don't set gdbarch_gdb_signal_{to,from}_target.
