The Ninja generator does not know how to append archives, so cannot split long archives into multiple commands. This means that the Ninja build fails with errors like "Argument list too long." It's possible to work around this issue by forcing the use of response files, which pack the archive filenames into a file and then pass that filename to the linker.
