That's really a nice approach; not only because it completely avoids the need
to echo and cluster the commands by using block level redirection, but also
because it clearly seperates _what_ needs to be done (in the recipe) from
_where_ it needs to be done (by defining SHELL and .SHELLFLAGS as scoped
variables).
Thanks a lot for sharing this! Cheers,
Chris

You may find this a better way in general, or at least an interesting
alternative. Requires 3.82 though:
.PHONY: all tgtA tgtB
tgtB: SHELL := /usr/bin/ssh
tgtB: .SHELLFLAGS := <remote-host>
all: tgtA tgtB
tgtA:
@echo Building $@ on $(shell hostname)
tgtB:
@echo Building $@ on $(shell hostname)
This test case works fine for me (once <remote-host> is filled in).
