	* libgtop-sysdeps.m4:
	* sysdeps/freebsd/msg_limits.c:

	Use configure checks to detect whether we need to define either
	KERNEL or _KERNEL to get the definition of 'struct msginfo' in a
	BSD system.  This replaces the previous checks in the code that
	relied on __FreeBSD__ and similar macros.

	Before this change, the explicit definition of _KERNEL in the
	msg_limits.c file broke the build in NetBSD because it made the
	system headers pull in stuff unavailable to userland.

	Fixes bug #337207.
