I have replaced the cc-options line in llvm-base.buildinfo.in by:

cpp-options: -DTARGET=@llvm_target@
cc-options: @llvm_cppflags@


I do not know whether the Haskell code also needs the preprocessor 
definitions that are intended for the C++ compiler. If yes, then 
@llvm_cppflags@ must remain in cpp-options.

With this change the Haskell modules and the cbits can be compiled, but I 
get the linker error:

/usr/local/llvm-3.0/lib/libLLVMipo.a(IPO.o): In function `LLVMAddAlwaysInlinerPass':
IPO.cpp:(.text+0x410): multiple definition of `LLVMAddAlwaysInlinerPass'
dist/build/cbits/extra.dyn_o:extra.cpp:(.text+0x1440): first defined here
/usr/local/llvm-3.0/lib/libLLVMScalarOpts.a(Scalar.o): In function `LLVMAddBasicAliasAnalysisPass':
Scalar.cpp:(.text+0x260): multiple definition of `LLVMAddBasicAliasAnalysisPass'
dist/build/cbits/extra.dyn_o:extra.cpp:(.text+0x13d0): first defined here

I can get rid of them by removing LLVMipo and LLVMScalarOpts from the 
generated llvm-base.buildinfo and continue installation with

$ cabal build; cabal haddock; cabal copy; cabal register

I do not know, why the libraries LLVMipo and LLVMScalarOpts were added to 
Extra-Libraries.
