[Buildroot] [May15 patch 12/12] netsnmp: disable build with external toolchain

[Darcy L. Watkins <dwatkins@tranzeo.com>]

Hello,

The fourth chunk in the buildroot-libtool.patch appears to be bogus.  It
adds a commented out chunk of code, but doesn't remove what appears to
have been intended to be the code to comment out (around line # 29xx in
ltmain.sh).  It would seem that an "exit 1" was replaced with "exit
$EXIT_FAILURE" so the patch broke.  I think it's possible that the patch
was refreshed without anyone catching this.

I also notice what appears to be two different variants of ltmain.sh
floating around in the packages - one circa 2007 (ver 1.5.24), the other
circa 2008 (ver 2.2.6).  Only the former is compatible with the patch.

The ltmain.sh in the netsnmp package is the newer one (not compatible
with the patch).  Do we need a variant of buildroot-libtool.patch for
the newer libtool, or is the newer ltmain.sh variant supposed to have
the cross compile problems fixed?

Regards,

Darcy
