There's nothing stopping you from specifying an explicit shell in your Makefile (see: https://www.gnu.org/software/make/manual/make.html#Choosing-...).

You could set it to Ash, Bash, Perl, Python, execline, Docker exec, or whatever you want really. You can also set that variable on a per-recipe basis, if you have one recipe that needs a custom shell.

(note to any GNU Make maintainers who might see this: it would be really helpful to be able to set .ONESHELL on a per-recipe basis as well!)
