A dependency on the system libraries can be coming from Chrome, or
from any of the shared libraries that it does depend on. If you first
delete out/ and then do a build, you can tell if the bundled versions
of those libraries are getting built by the .o files that will appear
in out/

What's the output of:
% objdump -x out/Release/chrome | grep NEEDED
AGL
How about
% cd /usr/lib/pkgconfig
% grep bz2 *
?
