Multiple test faliures on 32-bit Linux systems.

I ran validate with HEAD (e01367ff) on 3 different 32-bit Linux boxes and I'm seeing different failures on each one. I was advised on IRC to create a ticket with all the failures.

The first and third box are using the binary of 7.6.3 provided on the GHC site. I had to link libgmp.so.3 to libgmp.so.10 on both of these in order to get it to install properly.

Please ask about any info that I have not provided below!

As discussed on the mailing list, the Haddock numbers still need tweaking even after Austin updated them the other day. T1969 failure seems to come and go.

Second box: Linux yuuki 3.11.4-gentoo #1 SMP Tue Oct 8 00:19:37 BST 2013 i686 Intel(R) Core(TM)2 Duo CPU E8400 @ 3.00GHz GenuineIntel GNU/Linux Happy Version 1.19.3 Copyright (c) 1993-1996 Andy Gill, Simon Marlow (c) 1997-2005 Simon Marlow Alex version 3.1.3, (c) 2003 Chris Dornan and Simon Marlow

I installed the bootstrapping compiler on this box from Gentoo's package manager so I'm not sure how gmp is linked here. I can retry by boostrapping from binary and linking libgmp.3 to libgmp.10 (like the other boxes did) for consistency. The version of this complier is 7.6.3-r1.

A different Haddock perf failure, T1969 seems to have failed again and a totally new failure, T7859.

Whole plethora of failures! Haddock numbers again and a bunch of other stuff.

Considering how close 7.8 is, I think these should be looked at (especially that last set doesn't look too good).

I notice that over 2000 more tests were skipped on the first box (this is my day-to-day use computer). How are the tests to be skipped determined?
