Alexander,
     On fink, we having building llvm svn as follows for years without issue...

cd llvm-3.4

The fink build system doesn't set CFLAGS or CXXFLAGS but does set CPPFLAGS to "-I/sw/include"
and LDFLAGS to "-L/sw/lib". MACOSX_DEPLOYMENT_TARGET is set to "10.8" during the build on
darwin12.
   If I use...

cmake -DLLVM_BUILD_32_BITS:BOOL=OFF -DLLVM_TARGETS_TO_BUILD=X86 -DCMAKE_INSTALL_PREFIX=%p/opt/llvm-%v -DLLVM_ENABLE_ASSERTIONS=OFF -DCMAKE_BUILD_TYPE=Release -DCMAKE_OSX_SYSROOT:STRING=/ -DCMAKE_OSX_DEPLOYMENT_TARGET:STRING="" ..

...the build completes but setting -DCMAKE_OSX_DEPLOYMENT_TARGET to a null string hasn't been required in the past. What happens to your
cmake build if you set the MACOSX_DEPLOYMENT_TARGET target environmental? You should see the failure...
