I have never done this and others likely have more specific advice here. 
Base lives inside the GHC repository here [1]; there are general GHC 
development instructions here [2]. For specific advice and to what 
extent you really need to rebuild GHC in order to test a modified 
'base', I redirect you to the ghc-devs mailing list [3] and the GHC 
matrix room [4].
