---------------------------------+------------------------------------------
 when doing a build with THREADS=1, we are getting
 things like:
 {{{
 inplace/bin/ghc-stage1 [...] -c
 libraries/time/./Data/Time/Calendar/Days.hs [...]
 /home/ian/ghc/git/ghc/libraries/base/dist-
 install/build/Data/Typeable/Internal.dyn_hi
 Declaration for mkTyConApp
 Unfolding of Data.Typeable.Internal.mkTyConApp:
   Failed to load interface for `GHC.Fingerprint'
   Perhaps you haven't installed the "dyn" libraries for package `base'?
   Use -v to see a list of the files searched for.
 /home/ian/ghc/git/ghc/libraries/base/dist-
 install/build/Data/Typeable.dyn_hi
 Declaration for mkTyCon
 Unfolding of Data.Typeable.mkTyCon:
   Can't find interface-file declaration for variable
 GHC.Fingerprint.fingerprintString
     Probable cause: bug in .hi-boot file, or inconsistent .hi file
     Use -ddump-if-trace to get an idea of which file caused the error
 }}}

 (we only have Fingerprint.dyn_hi-boot). GHC still exits successfully,
 however.
