Allow for multiple linker instances
Fixes the Haskell portion of #3372. Allows for multiple linker instances.
TODO:
-
commits are either individually buildable or squashed -
commits have commit messages which describe what they do (referring to Notes and tickets using #NNNN
syntax when appropriate) -
have added source comments describing your change. For larger changes you likely should add a Note and cross-reference it from the relevant places. -
added a testcase to the testsuite.
