Well, I though we have a policy to remove bundle dependencies in order
to avoid building the same library many times. Do we make exceptions for
shared libraries w/o a build system? (an exception I can think of is
gnulib)

Besides, the FIXME comment seems to suggest future readers to help
remove the bundled pnglite. Debian also removes the bundled pnglite in
teeworlds[0].

Thanks for all the feedback!
