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 

Thanks a lot for sharing this! Cheers,

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

        @echo Building $@ on $(shell hostname)

        @echo Building $@ on $(shell hostname)

This test case works fine for me (once <remote-host> is filled in).
