 I'm trying to build a mingw32 cross compiler.
 I configured with `./configure --target=x86_64-x64-mingw32`, then I built
 with `make -j 1`.
 The build then fails with the message ` #  error "Threads not supported"`
 followed by some other errors. (The last part of the make log is attached)

 To bypass #9542, I deleted the following lines from utils/hsc2hs/Main.hs:

 {{{
 #if defined(__GLASGOW_HASKELL__) && !defined(BUILD_NHC)
 #include "../../includes/ghcconfig.h"
 #endif
 }}}
