That's the R_ARM_V4BX problem I mentioned here:
http://lists.debian.org/debian-haskell/2013/05/msg00054.html
It isn't a TH failure as such, just one that comes up a lot whenever TH
or GHCi is involved. I don't know why it happens to show up in that
particular place, but it's certainly possible that the missing handling
of this relocation would account for more than just the GHCi-related
failures on armel (not armhf).
The patch in my above post should fix this, if anyone can test it. For
us, it's safe to entirely ignore the relocation like this because Debian
armel is (AIUI) ARMv4t at minimum anyway so we have no need for this
specialised relocation that's used for fixing things up to work on plain
old ARMv4. Even for upstream, I think the chances of anyone caring
about running modern Haskell code on a StrongARM are pretty limited
given that current distributions don't tend to support them.
