Comment (by osa1):

 cnmne, if you want to help with debugging this doing the follwoing would
 be really helpful:

 - Clone a fresh GHC and cd into the directory
 - `cp mk/build.mk.sample mk/build.mk`
 - Edit `mk/build.mk`, add `GhcDebugged = YES` somewhere in that file
 - Build with `./boot && ./configure && make`
 - Edit `inplace/bin/ghc-stage2` to add `+RTS -DS -RTS` at the end of the
 last line (the line starting with `exec ...`)

 ghc-stage2 is now a debug build with sanity checks enabled. Now install
 everything again (whatever you need to install to reproduce this) but pass
 `--with-ghc=path-to-ghc-stage2` to cabal in each command. Hopefully you'll
 get a better error message.
