insmod: build fix for microblaze (by Greg Steuck <greg AT nest.cx>)

two fixlets for -Wall

fix bug 2704: remove verbatim RFC text from source
(this creates problems for Debian).

- accept ip l s ib0 addr 00:00:00:00:00:00:00:00:00:00:00:00:00:00:00:00:00:00:00:00

- very minor shrinkage
  odd that this saved 1byte. And there could be something wrong with
  ifcombine or the like since omitting the braces produces bigger code?

- add appropriate string for arp header #32 for use by ip(8)

- fix bug where we incorrectly rejected ifconfig eth0 hw ether $whatever
- add support for printing ipoib to ifconfig

- fix compilation on x86_64

- mention duplication of in_ether()

- provide proc-less sample
- improve wording

testsuite instrumentation fixes by Christian

Add more -W options to gcc.

more of -Wall fixes from Cristian Ionescu-Idbohrn.
