[wplug] Kernel build bug

[Weber, Lawrence A]

Thanks, I ran into this several other times in the build and it became
obvious that "fixing" the Makefile was the wrong thing to do.

According to the tree at
<http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.25.y.git;a=t
ree;f=net/ipv4/netfilter;h=72d3e0f1788a138b2fad12fa5bf78c86197e7a00;hb=1
420f09c0b8a88f9df2034e6ba04fcc4c3f6925e>,
/net/ipv4/netfilter/ in 2.6.25.1 contains BOTH ipt_ecn.c and ipt_ECN.c.
If you're missing one of them, it may have gotten wiped out by a
case-insensitive archive tool or filesystem.

It doesn't look like any ECN lines in the Makefile have changed in the
past year or so, so if it contained such a gross error I would have to
hope that would be plenty of time for it to be caught.
