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.

	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.
