New description:

 When building 3a18baff06abc193569b1b76358da26375b3c8d6 with profiling, GHC
 emits this error:

 {{{
 ghc-stage1: panic! (the 'impossible' happened)
   (GHC version 8.1.20170106 for x86_64-unknown-linux):

 Please report this as a GHC bug:  http://www.haskell.org/ghc/reportabug

 compiler/ghc.mk:582: recipe for target
 'compiler/stage2/build/StgCmmMonad.p_o' failed
 }}}

 I have attached my `build.mk` file.  It may be wrong, but I don't think it
 includes anything that should break GHC.  Even if it did, I should get
 some sort of error message, not a panic.
