Mach-O ld64 supports -w to suppress warnings. GNU ld 2.40 will support the option as well (https://sourceware.org/bugzilla/show_bug.cgi?id=29654). This feature has some small value. E.g. when analyzing a large executable with relocation overflow issues, we may use --noinhibit-exec --emit-relocs to get an output file with static relocations despite relocation overflow issues. -w can significantly improve the link time as printing the massive warnings is slow.
