I just build 7.6.1 release on my ubuntu 12.04.1 LTS which is hard-float 
ABI distro. I used distro provided LLVM 3.0 and configured GHC with:

./configure --with-llc=/usr/bin/llc-3.0 --with-opt=/usr/bin/opt-3.0

And resulting ghc-stage2 is not only able to complete the build but also 
builds HelloWorld example which runs fine:

Please keep in mind that GHC HEAD is completely different beast as there 
is new codegen put on by defaul there and LLVM codegen is not working 
correctly with it yet. Anyway, Austin Seipp seems to be working on 
fixing that.
