Which arm do you have?

gentoo-haskell overlay got arm v5 binaries recently. I haven't
got to test it on armv7 yet, but I expect it to work.

https://github.com/gentoo-haskell/gentoo-haskell/blob/700677545a4e8b2f583c3641b99cd4c9588e9655/dev-lang/ghc/ghc-7.0.4.ebuild

Gentoo uses ghc built against glibc, but I think it's feasible to bootstrap
to non-glibc host as well. You would need to have 2 toolchains simultaneously
so some sorts of hacks is required.

Do you really need uclibc? Ghc is a relatively heavyweight thing.
I would expect a need to path ghc to run it there.
You might also like to look at jhc. It is able to cross-compile to
other targets, but it's not a drop-in replacement of ghc.

Ebuilds are hidden in haskell overlay (accessible via layman).
