It looks like the recent differential builds are all failing like this:
compiler/main/DynamicLoading.hs:79:19: warning: [-Wunused-matches]
Defined but not used: ‘hsc_env’

ghc: panic! (the 'impossible' happened)
(GHC version 8.2.1 for x86_64-unknown-linux):

Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug
make[1]: *** [compiler/stage1/build/PrelRules.o] Error 1
make[1]: *** Waiting for unfinished jobs....
make: *** [all] Error 2
Oddly, I don't see a commit to master failing like this. What's going on?
