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,
