last commit on master broke libubacktrace build

[Filippo ARCIDIACONO]

Hi all,
last commit 71c10c484e7dc113396cccb7e503befb759c6346 
</uClibc/commit/?id=71c10c484e7dc113396cccb7e503befb759c6346>,
(libubacktrace: fix backtrace for statically linked application)
broke libubacktrace's build.
The module backtrace.o[sS] was not built.
I'm going to post a patch to fix this issue.
Sorry for the inconvenience.

Regards,
Filippo
