Yes. You change the SHELL make variable and then invoke debugsh
doing whatever you want and then runs the actual shell command. Tested:

$ cat Makefile
all:
        @echo foo
        @ls Makefile debugsh 2>/dev/null || true
$ cat debugsh
#!/bin/sh

echo '===> Type Enter to execute sh' "$@"
read dummy
exec sh "$@"
$ chmod 755 debugsh
$ gmake
foo
Makefile        debugsh
$ gmake SHELL=debugsh
===> Type Enter to execute sh -c echo foo

foo
===> Type Enter to execute sh -c ls Makefile debugsh 2>/dev/null || true

Makefile        debugsh
