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
