Improve dependency lookup of multithreading feature
As it came up in a discussion in !233 (merged), the dependency lookup for the MULTITHREADING
feature could be improved.
In @peanutfun's words:
The whole dependency lookup for multithreading is quite messy now. I'd like to rewrite it, with the idea of creating a find module for a "meta-package"
PSTL
which looks up the ParallelSTL definitions.
