PATCH: remove some casts from bucomm.c

[Ben Elliston]

This patch changes the type of some local variables from int to enum
bfd_architecture (as they should be) and consequently eliminates some
extraneous casts.  OK for mainline?

2006-03-13  Ben Elliston  <bje@au.ibm.com>

	* bucomm.c (display_target_list): Make local variable `a' to be of
	type enum bfd_architecture.  Thus no need to cast enums to int.
	(display_info_table): Likewise.
