freebsd/sys/conf/Makefile.i386
Garrett Wollman 6bf5b24768 Don't include options MULTICAST or MROUTING in generic kernels. MULTICAST
has no effect now, and MROUTING should never be defined by default.
(Eventually the code should be dynamically loadable.)

Also, allow for Pentium CPUs in GENERICBT kernels.

Add an `install' rule to Makefile.i386, which looks like this:
	mv /kernel /kernel.old
	install -c -m 555 -o root -g root -fschg kernel /
I'd like comments on whether or not you think it's a good idea to have
the kernel be immutable by default; I'm happy either way.

# This makefile is constructed from a machine description:

# Generic makefile changes should be made in
