[Buildroot] Fixing linux-pam build failures

["Stefan Fröberg" <stefan.froberg@petroprogram.com>]

Hi Dmitry!

Your work on this pam support looks good.

I have attached in this message my very quick, unpolished & very very
very dirty pam (version 1.1.5) hack
(it doesn't bother to even check for if pam is enabled in busybox and it
assumes that pam.d stuff is already in fs/skeleton/etc )

I can't even remember when I did this ugly hack.

Got it somehow working with the help of :
http://www.linuxfromscratch.org/blfs/view/svn/postlfs/linux-pam.html
http://www.linuxfromscratch.org/blfs/view/svn/postlfs/shadow.html
and
http://www.linuxfromscratch.org/blfs/view/svn/postlfs/cracklib.html

Those Linux From Scratch pages are really great starting templates for
any new buildroot package!
:)

Also, those three patches mentioned in this attached file are from
openwrt project witch also
uses buildroot  stuff (???).

https://dev.openwrt.org/browser/packages/libs/libpam

If you find something usefull for your work then by all means salvage
what you need from it.

I just want to get quickly rid of my dirty pam hack as soon as official
support lands on buildroot.

Stefan

P.S:

Your work for v86d ( http://patchwork.ozlabs.org/patch/157286/ )
is working wonderfully in my distro !
Thanks!
