cover perfer older version of lttng-ust in poky distro

Set the PREFERRED_VERSION of lttng-ust to use lttng-ust instead of lttng2-ust in poky distro. This fixed yocto bug #2062.

The lttng2 is very different in terms of architecture and usage model, compared to lttng. The eclipse upstream lttng plugin won't be able to support lttng2 until the eclipse Juno release(Jun 27th, 2012).

This patch seems to break the lttng-2.0/lttng-tools build. Please verify that we can build lttng-2.0 bits or somehow handle both.

I am not sure the kernel will support the older lttng, in which case using lttng-ust from the older release will not work, so we can not use the eclipse with it anyways.

It won't. Since lttng 1.x wasn't ported past 2.6.38 (and released), since lttng was moving to 2.x and the new CTF, there wasn't any sense in porting it ourselves.

That being said, it IS possible for both 1.x and 2.x to co-exist, but we don't have the weeks (or the value) in making the port.

Cheers,

Bruce

Just like Bruce said, I double checked that the older lttng-ust 1.x can work upon new kernel 3.2.11. So Saul, please ignore this patch. I'll send another patch to oe-core to change the name of new 2.x lttng-ust to lttng2-ust, so that it's possible to have them co-exist.
