iptables -git automake warnings

iptables -git automake warnings

[Patrick McHardy]

I get this with the current iptables -git version:

Makefile.am:7: `:='-style assignments are not portable
Makefile.am:71: `:='-style assignments are not portable
Makefile.am:72: `:='-style assignments are not portable
Makefile.am:73: `:='-style assignments are not portable
Makefile.am:74: `:='-style assignments are not portable
Makefile.am:75: `:='-style assignments are not portable
Makefile.am:78: `:='-style assignments are not portable
Makefile.am:80: `:='-style assignments are not portable
Makefile.am:97: `%'-style pattern rules are a GNU make extension

Additionally compilation aborts with:

make[2]: *** No rule to make target 
`../include/linux/netfilter_ipv4/ipt_DSCP.h', needed by `libipt_ECN.oo'. 
  Stop.

This is resolved by using a fresh clone.

(iptables still requires GNU make for extensions/, because it is
so much easier to write.)

Must have been a really old tree, since no .c file besides
libipt_DSCP.c (long renamed libxt_DSCP.c) ever used ipt_DSCP.h.

Possibly, I usually don't delete the tree. The error didn't happen
previously for some reason.
