[lttng-dev] Support for new arch 'ppc64le'

[ravi]

Hi,

        We are in the process of adding support for new architecture 
'ppc64le' (PowerPC 64 Little Endian) and as part of that, We have worked 
with libtool maintainer to get alpha release (links below) which has all 
the needed bits to support building on ppc64le arch.
ftp://alpha.gnu.org/gnu/libtool/libtool-2.4.2.418.tar.gz(1.6MB)
ftp://alpha.gnu.org/gnu/libtool/libtool-2.4.2.418.tar.xz(920KB)
(A stable libtool release is expected soon this year)

' userspace-rcu-0.8.1' didn't build on 'ppc64le' system because of 
outdated libtoo.m4/config.guess files.
Latest ' liburcu' source package we picked is from : 
http://lttng.org/files/urcu/userspace-rcu-0.8.1.tar.bz2

Along with changes to libtool related files,  we have found a patch 
available in ubuntu src repo, which is required to build 'liburcu' 
successfully on 'ppc64le' system.
Im attaching the same patch which is created on top of "liburcu-0.7.7-1"...

hence we request you to apply attached patch , and spin off a new 
version of 'liburcu' using the latest libtool alpha release . So that we 
can test ppc64le fixes.
Your response is highly appreciated
