Build extra sources as a standalone BuildM action
Browse files Browse the repository at this point in the history
Refactors the duplicated `buildExtraSources` function from `gbuild` and
`buildOrReplLib` into a standalone monadic computation in the context of
building a component (namely, a 'BuildM' action). This refactor allows
us to share the code for building an extra source amongst the two
functions, and paves the way to fixing haskell#9389.
