Off-list someone sent me this:

define RULE-pkg
$(notdir $(1)): $(filter $(1)/%, $(elcs))
endef

$(foreach pkg, $(pkgs), $(eval $(call RULE-pkg, $(pkg))))

Which seems to work! Called with the bare package name. One weird thing,
though, is that for each file being compiled I get:

Unable to activate package ‘relint’.
Required package ‘xr-1.19’ is unavailable
Unable to activate package ‘exwm’.
Required package ‘xelb-0.18’ is unavailable
Unable to activate package ‘ebdb-i18n-chn’.
Required package ‘pyim-1.6.0’ is unavailable
Unable to activate package ‘counsel’.
Required package ‘swiper-0.13.1’ is unavailable

Which is odd since the package I'm compiling doesn't have anything to do
with those packages.

But, closer to success.
