--------------------------------+----------------------------------------
 I'm attempting to build the ghc-8.6 branch on ARM linux.  I have GHC 8.2.2
 and LLVM 6.0.1 installed.

 My only build.mk change is to set BuildFlavour=quick

 I've made it as far as "final phase" where I get the following failure:
