 As you can see, no -L/usr/lib is given on the command line, but still it
reaches the compiler. That's because libtool wasn't patched, and that is because
you used libtoolize/autogen.sh which overwrites the patched libtool files.

 The solution is not to use autogen.sh. Instead, set GST_SHARK_AUTORECONF = YES
in the .mk file. Buildroot's autoreconf will take care of patching the libtool
files.

 You may have a problem because the downloaded tarball doesn't contain the
common/ submodule. The best solution for that is to not use the tarball
download, but instead use the git download method:

GST_SHARK_SITE = https://github.com/RidgeRun/gst-shark
GST_SHARK_SITE_METHOD = git
GST_SHARK_GIT_SUBMODULES = YES
# Downloaded from git, no configure script
GST_SHARK_AUTORECONF = YES


 Regards,
 Arnout
