Build failure on s390(x): Don't know if ArchUnknown is 32bit

[nomeata]

Hi,

the 7.4.1 release candidate failed to build on s390(x); previous versions built fine. It would be great if s390(x) support would not be dropped, if it can be helped:

 https://buildd.debian.org/status/fetch.php?pkg=ghc&arch=s390&ver=7.4.0.20111219-2&stamp=1324640606 and  https://buildd.debian.org/status/fetch.php?pkg=ghc&arch=s390x&ver=7.4.0.20111219-2&stamp=1324642276

The s390 port is 32 bit (or is it 31? anyways, it has worked before), while the s390x port ist 64 bit.

Thanks, Joachim on behalf of the Debian Haskell Team

The patch at  http://anonscm.debian.org/darcs/pkg-haskell/experimental/ghc/patches/S390-Arch lets the build continue, but then the build on s390x is affected by #5731:  https://buildd.debian.org/status/fetch.php?pkg=ghc&arch=s390x&ver=7.4.0.20111219-3&stamp=1325273960

That should be #5732, sorry.

    Store the word size as determined by configure, in the settings file (#5735)
    
    Now target32bit works for all targets without any manual intervention,
    as it should do.  #5735 was a portability regression.
