Ok, new wiki page is here:

Is:
--with-gcc=<gcc> --with-ld=<ld> --with-nm=<nm> --with-objdump=<objdump>
Necessary? I guess if the given tools are not on PATH with the normal
cross-compiling prefix?
Right, I didn't know that autoconf would automatically look for the
tools as <platform>-tool. I'll update the docs.
Please edit away. In particular I haven't investigated
cross-compiling with LLVM
That's a bit broken right now (since GHC doesn't pass through the target
to LLVM), but otherwise just involves having an LLVM that supports the
target on PATH.
Also:
cabal --with-ghc=<cross-ghc> --with-ld=<ld> ...
What does this do? So far I've been careful to use a seperate
~/.cabal-blah directory to not entangle my two cabals. Will it handle
things nicely? Do you need to tell it where to find ghc-pkg, or will
--with-ghc work for that? Maybe I can switch to just a script/alias
instead of a whole config file :)
Ah, in my case the GHC I built was called ghc-7.7.20130116, so it didn't
clash with anything else in .cabal. You could also configure your cabal
to put the arch/os in the directory name.
Cheers,
Simon
