[lttng-dev] More LTTng problems

[Henrik Hautakoski]

Oh yeah. for the record.

DEBUG1: Using 32-bit UST consumer at:
/opt/xcompile/powerpc-e500-linux-gnu-lttng/lib/lttng/libexec/lttng-consumerd
[in spawn_consumerd() at main.c:1776]
Error: Spawning consumerd failed

I tried to change the patch with --consumerd32-path flag after. but it
did not change the result.
