Merge bitcoin/bitcoin#21874: fuzz: Add WRITE_ALL_FUZZ_TARGETS_AND_ABORT
fa5cb6b268554fe0f272833794a98106872ac6a5 fuzz: Add WRITE_ALL_FUZZ_TARGETS_AND_ABORT (MarcoFalke) Pull request description: This is needed when stdout is polluted by the fuzz engine. stderr can't be used instead because it is polluted by aborting the program. Top commit has no ACKs. Tree-SHA512: bf0a2a6bcd964ff1f0f3ef6e7e297b4c780430c4d6312332ed99ace0e1c58243c1483fd387e39405837d39b36072dfeb9ae03d2a7aa728ad6955159754fd5766
