Just tried swapping all references to /bin/sh to /bin/pdksh instead -- the config script ran just fine and musl was built correctly (with the added CFI data). Same with /bin/dash. Thanks for the idea -- I will keep it in mind next time I am writing shell. Maintainers: is there still anything blocking this patch from getting merged in? Please let me know so I can fix any remaining problems. Thanks, Alex Dowad
