Right--along with the empty string :).

Are you sure? I'm surprised because there's some code in job.c which
checks the value of the SHELL variable to see whether it looks like a
valid shell; it basically does a strcmp() with "/bin/sh" and if it's
different it uses the slow path.
If this is broken we should definitely investigate.
Hm, I just ran a test and I don't think it invoked a shell:
SHELL = /bin/sh
all: ; @echo hi
