[PATCH 1/7] Implement the gdbarch.{sh,c,h} bits.

[Sergio Durigan Junior <sergiodj at redhat dot com>]

This patch basically implements the necessary bits to the new
gdbarch_gdb_signal_to_target function.

2013-07-26  Sergio Durigan Junior  <sergiodj@redhat.com>

	* gdbarch.sh (gdb_signal_to_target): New function.
	* gdbarch.c: Regenerate.
	* gdbarch.h: Regenerate.
