ANYPS5_BUILD_FUZZERS builds relinker_conversion_fuzzer with AddressSanitizer and UndefinedBehaviorSanitizer in relinker-only Clang builds on Linux. The first input byte selects the target system, --to-intel and the unused-filter level; the rest is the executable passed to Conversion::Convert, the path the web converter takes. tools/relinker_fuzz_seeds.py writes the relinker test fixtures as seeds, and CTest runs a short smoke run.
