[PATCH 3/3] Testcase

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

This patch implements the testcase for this fix.  The test is very
simple: we just have to verify if the syscall number for each
architecture has different meanings.  I chose to test i386 and x86_64
here, but it could be any other architecture supported by the "catch
syscall" command.

	PR breakpoints/10737
	* gdb.base/catch-syscall.exp (do_syscall_tests): Call
	test_catch_syscall_multi_target.
	(test_catch_syscall_multi_target): New function.
