I've reverted this change and committed updated library dependencies.

Usually the problem you found is caused by obsolete library
dependencies. Just restarting the build is enough for fixing the problem
*if* you are building all LLVM targets.

cmake/modules/LLVMLibDeps.cmake is regenerated every time a build that
includes all LLVM targets finishes building the libraries. However, the
tools keep using the old library dependencies until the next build. You
can see LLVMLibDeps.cmake as a modified file on `svn status'. The right
thing to do in this case is:

1. Delete all libraries from the build directory.
2. `make' again.
3. Check that LLVMLibDeps.cmake was really changed.
4. Commit it.

The first two steps are necessary just in case some library was renamed
or removed. The script that generates the library dependencies work on
existing library files on the $BUILD/lib directory, so any stale file
there will be included on its output.
