[meta-freescale] [meta-fsl-arm PATCHv2 4/4] linux-imx (2.6.35.3): Enable tracing support so lttng's modules are build

[Otavio Salvador]

lttng support is enabled in Freescale test images however its modules
were not being build due lacking of tracing support in the
kernel. This patch enables the needed kernel features to allow the
modules to be build and thus making lttng usable.
