commit d7a76c6b6460efa26c690aaa97a1843c9391d19f Author: Jon Turney <[email protected]> Date: Tue Dec 13 23:17:48 2022 +0000 Cygwin: configure: Add option to disable building 'dumper' Rather than guessing, based on just the presence of libbfd, add an explicit configuration option, to build dumper or not, defaulting to building it. This might have some use when bootstrapping Cygwin for a new architecture, or when building your own Cygwin-targetted cross-compiler, rather than installing one from the copr, along with the dependencies of libbfd.
