I'm afraid not.  The way I approach similar situations is this pattern:


<code>

ifeq (...)

define target._conditional-piece
bar
endef

else

define target._conditional-piece
baz
endef

endif

###

target:
	foo \
	| $(target._conditional-piece)

</code>


The main advantage IMO is for debugging; ie when your run `make -pnr
target' the output contains only the version of `target._conditional-
piece` which you'd be interested in based on the condition.  Much in
the same vein as your pseudo-code.

Additionally, I find this easier to adapt than converting all to
.ONESHELL.  YMMV
