Which exact NodeJS modules withing the pile of modules provided by our 
"node-acorn" package is actually needed by nodejs?

I suspect breaking the loop might be simpler (fewer parts need to be 
provided in source form) if knowing what exactly is needed.

Simplest might be to embed a copy of needed module(s) in the source 
package of nodejs either as a component or below debian/missing-source. 
Such embedded library should then be used only when building in 
bootstrapping mode, and for regular builds a build-dependency on the 
separately maintained library is used.
