I think I probably built those, but around the release of 3.4.2, I 
upgraded my machines to trusty.

I think instead, you may want to look here:
http://llvm.org/apt/

Which are properly packaged (but don't forget the gcc-4.8 backport for 
precise).

If you want to build it yourself in the same way the "release" binaries 
are built, you'll need to check out the llvm source and invoke:
./llvm/utils/release/test-release.sh -release 3.5.0 -final -triple 
x86_64-linux-gnu -no-64bit

This will build a compiler, use that compiler to build another compiler 
and then use that compiler to build the final compiler, which will be 
packaged into the xz file.  This may not actually be what you want, but 
it's nice for testing.

On a 64bit platform, the -no-64bit actually means "don't build the 64bit 
version twice".
