GHC 8.1.20160111 fails to bootstrap itself.

Hello, bootstrapping GHC HEAD with HEAD is broken. The failure looks like:

libraries/binary/src/Data/Binary/Builder/Base.hs:67:0: error:
     missing binary operator before token "("

libraries/binary/src/Data/Binary/Builder/Base.hs:114:0: error:
     missing binary operator before token "("

libraries/binary/src/Data/Binary/Builder/Base.hs:123:0: error:
     missing binary operator before token "("
`gcc' failed in phase `C pre-processor'. (Exit code: 1)
gmake[1]: *** [utils/ghc-cabal/dist/build/tmp/ghc-cabal] Error 1
gmake: *** [all] Error 2

I'm setting highest prio on this (as I feel) so lower this if you like.

Do you know whether this is broken on the ghc-8.0 branch as well?

For me ghc-8.0 (from a few days ago) can bootstrap itself. There may be other variables here, like whether CPP is clang. I think the error means MIN_VERSION_base(4,9,0) was not expanded for some reason.

1. 0.1 RC1 seems to build 8.0.1 RC1 just fine on i386/solaris 11.

verified that today's head is still not able to build the same head. At least not on Solaris 11/i386 platform.

This commit caused it: https://phabricator.haskell.org/rGHC351dea4a7c07#31880.

Instead of reverting that commit, I plan to fix bootstrapping with HEAD by enabling MIN_VERSION support without -hide-all-packages (see ticket:10970#comment:113772).

I just submitted as phab:D1897, and now I realised that we had a similiar idea... except you wanted this to work w/o -hide-all-packages (which tbh at this point I wonder why -hide-all-packages isn't acceptable).
