[lttng-dev] Compilation error with openwrt and uclibc 0.9.31

Hi,

I am using backfire version of Openwrt and would like to try to use 
profiling features bring by tools like lttng. I found some Makefile 
packages on openwrt website to build lttng-tools and lttng-ust with 
recent version of openwrt version but I am not able to compile lttng 
without error. with mine..

Environment :

Openwrt Backfire
UCLIBC 0.9.31
Linux kernel 2.6.28
ARCH mips32
lttng version : 2.3.0
librcu version : 0.8

First problem was related to lttng-ust-2.3.0/libringbuffer/getcpu.h. I 
get an undefined reference to c variable in lttng_ust_get_cpu function. 
After some research I was not able to find a solution about this point 
even if I seem to be up to date since I found some patch related to 
issue with old version of uclibc than 0.9.32. This patch seems to be 
already integrated in my lttng ust version. Anyway, I found a workaround 
to check that the next step on the compilation is find... but it is not...

Compilation result :

make package/lttng-tools/compile V=99

I am not very confortable with autotools but I am not able to understand 
this error. Is it relared to the missing liburcu-common.so.2 library ? 
shm functions are define by uclibc ? missing include ?

Thanks,
Arthur.
