So use gnatmake to build the library once, run gnatmake -M, and save
the results.

Write a dummy main to force gnatmake to do what you need, then
manually delete it from the final makefile. You could probably
automate this process in your favorite scripting language.

It might be possible to modify gnatmake to not require a main; try
reading the sources. It clearly does most of what you need!
