Patch to provide m68k simulator to gdb

[Will Cohen <wcohen@redhat.com>]

DJ Delorie and I have integrated the m68k emulator from the Un*x Amiga
Emulator (UAE) with gdb. UAE is GPL'ed software. The ChangeLog entries
and patch file are attached to this mail.  I would like to get this
incorporated into gdb. Other people might find this patch useful.

Subject: [RFA] gdb testsuite changes
Date: Tue, 27 Feb 2001 15:11:00 -0000

These changes were motivated by a port of gdb to target an 8 bit
processor with 2 byte integers, no C++, no long long, and very limited
memory.

ChangeLog entry:

	* gdb.base/annota1.exp: Move test of isnative to earlier in the
 	file -- to prevent failing when the compile fails but we have no
 	intention of running the tests anyway.

	* gdb.base/long_long.exp: Test target_info for no_long_long, skip
	tests if set.

	* gdb.base/maint.exp: Support 2 byte integers as well as 4 byte
 	integers.

	* gdb.c++/ctti.exp: Skip tests if skip_cplus_tests returns true.
	* gdb.c++/namespace.exp: Ditto.

Okay to commit?
