To make instrumented shared libraries work with afl-clang-lto you have to do
quite some extra steps.

+Every shared library you want to instrument has to be individually compiled.
The environment variable `AFL_LLVM_LTO_DONTWRITEID=1` has to be set during

Additionally the environment variable `AFL_LLVM_LTO_STARTID` has to be set to

E.g. for the first shared library this would be `AFL_LLVM_LTO_STARTID=0` and
afl-clang-lto will then report how many edges have been instrumented (let's say
it reported 1000 instrumented edges).
The second shared library then has to be set to that value

This is quite some hands-on work, so better stay away from instrumenting
shared libraries :-)
