Bugzilla Bug 99810

I'm trying to build a minimal gentoo-linux system using uclibc profile, but 
linux 2.6.12 requires gettext to build its configuration modules.

With 2.6.12 linux include Kconfig i18n support, see on linux.org 
commit 3b9fa0931dd86a1fe5507311ee8031650f5d0e8c

on a minimal system without gettext installed it is impossible to configure and 
then compile a 2.6.12 kernel

i18n removal patch

The attached patch removes i18n from Kconfig. After applying the patch I was
able to configure the kernel.
I think that this patch should be applied from the kernel sources ebuilds if
the gettext USE flag is not present.

This really should go onto the LKML for discussion - we'd rather not include
patches that revert upstream-specified behaviour without a better solution
getting implemented.

sources-nogettext.patch

Another patch, this one detects if there is no gettext on the host system and
disables its functionality, else all works like upstream.

2.6.13 i18n Reversal Patch

Try this patch instead.  I bumped into this while preparing Gentoo/MIPS SGI
LiveCDs (using a mipx/uclibc chroot for genkernel testing) and this on ereared
up and bit me.	So I hunted down the full commit done upstream and reversed it.
 This is the 2.6.13 patch, which should/may apply to 2.6.12.

2.6.14 i18n Reversal Patch

Here's the 2.6.14 version (against -rc2).

This is a blocker for any security bug which will present itself on 2.6.x
kernels and uClibc environments.

Yuri, where has this patch come from? It looks more acceptable than the others
floating around.

Made it myself and the auto detection idea is from vapier.

Ok. Have you sent it upstream?

No, but you kernel Gentoo guys please do so.

Ok, ignore the previous comment ;-)

On vapier's advise I submitted it upstream:
http://bugzilla.kernel.org/show_bug.cgi?id=5501

Also I made a tiny modification to the patch (in upstream bugzilla)

(I was kind of nervous about that as this is a kernel after all)

The correct way to submit patches is to send to the linux kernel mailing list
(see /usr/src/linux/Documentation/SubmittingPatches). I am happy to do this for
you if you want me to (and you will still get credited for it).

Fixed a typo that caused all systems to appear as not having NLS (checked for
the misspelled header file).
