gh-103776: Remove explicit uses of $(SHELL) from Makefile (GH-103778)

This avoids conflicting with the shebang of the called scripts as well
as avoiding hard errors on platforms where the called script runs a
failing unchecked command in the usual course of checking since
`SHELL=/bin/sh -e` as of a90863c.

Fixes gh-103776.
