Advice:  Don't do that! :}b

I'm a bit slow today, what is the problem with make using /bin/sh?

Make needs _something_ to interpret shell commands.  The ash shell which is
normally used for /bin/sh under Cygwin is a quicker shell than bash that is
sufficient for the sorts of things make wants a shell to do.
