[Haskell-cafe] Cross ghc-7.8.3 for PowerPC build fails

[Jon Schneider]

I finally got some PowerPC output but found it hung (on the target).

I suspected it might be that we're using an SPE rather than the more
common EABI but quickly found that it is due to
https://ghc.haskell.org/trac/ghc/ticket/7695, possibly to be fixed soon
according to the clear status notes for 7.10.1 and in any case easily work
roundable by providing a UTF-32.so .

Further good news is that what we want to do is purely mathematical
manipulating only bitmaps, already has an implementation with tests in
another language and ought to lend itself well to Haskell according to my
learned colleague. So we can now proceed with some gentle performance
testing on both our product platforms.

I assume that NGC is what you get by default. helloworld works with or
without -fvia-C when it clearly uses power---gcc.
