That script successfully built the stage2 compiler, and only eventually failed
building haddock:
/home/joeyh/tmp/ghc-7.8.3/compiler/stage2/build/libHSghc-7.8.3-ghc7.8.3.so: error: undefined reference to 'arm_atomic_spin_lock'
/home/joeyh/tmp/ghc-7.8.3/compiler/stage2/build/libHSghc-7.8.3-ghc7.8.3.so: error: undefined reference to 'arm_atomic_spin_unlock'
Those are guarded by a defined(arm_HOST_ARCH_PRE_ARMv6) so it should
be easy to fix.
Despite this failure, ghc seems to basically work. It can build hello world.
More impressively, ghci really works! So TH should work too.. On arm!

So looks like https://ghc.haskell.org/trac/ghc/ticket/7794 is really fixed too.
Now I'm trying to use this compiler to build the ghc package.
