[CMAKE] Build test_bitcoin_fuzzy
Summary:
Build the fuzzer glue executable.
Excluded from default build, as it makes no sense to build it without
instrumentation.
Test Plan:
WARNING: the test plan will require you to clear your ccache once done.
Needs D4578 to pass:
cmake -GNinja .. -DCMAKE_C_COMPILER=afl-clang-fast \ -DCMAKE_CXX_COMPILER=afl-clang-fast++ ninja test_bitcoin_fuzzy
Follow the instructions from fuzzing.md starting at section `Preparing
fuzzing` and check it runs as expected.
