 I am having problems building yi on 32 bit architectures (i386, hurd-i386,
 kfreebsd-i386) on Debian:

 GHCi runtime linker: fatal error: I found a duplicate definition for
 symbol
    __x86.get_pc_thunk.bx
 whilst processing object file
    /usr/lib/haskell-packages/ghc/lib/i386-freebsd-
 ghc-7.6.3/vty-5.2.1/libHSvty-5.2.1.a
 This could be caused by:
    * Loading two different object files which export the same symbol
    * Specifying the same object file twice on the GHCi command line
    * An incorrect `package.conf' entry, causing some object to be
      loaded twice.
 GHCi cannot safely continue in this situation.  Exiting now.  Sorry.

 It does not happen on amd64. This happens on the Debian auto-builders and
 I did not reproduce it locally yet, but maybe someone can already tell me
 what’s wrong from looking at it.
