[yocto] lttng-ust fails to build in current mainline for beagleboard.

[Enric Balletbò i Serra]

Hi all,

Seems the package lttng-ust fails to build in current mainline, is
currently the build for beagleboard broken ?

The log looks like:

ERROR: Function 'do_compile' failed (see
/home/eballetbo/Workspace/yocto/build/tmp/work/armv7a-vfp-neon-poky-linux-gnueabi/lttng-ust-0.15-r2/temp/log.do_compile.24087
for further information)
