This patch fixes the following error when trying to execute clang compiler
(host-variant):
CommandLine Error: Option 'x86-use-base-pointer' registered more than once!
LLVM ERROR: inconsistency in registered CommandLine options
The same happens for the other binaries, such as clang-format:
./clang-format
: CommandLine Error: Option 'help-list' registered more than once!
LLVM ERROR: inconsistency in registered CommandLine options
Clang binaries are tools, and given that DLLVM_LINK_LLVM_DYLIB is set,
they are linked against libLLVM.so. The problem is that binaries are
also linking against some LLVM static libraries, resulting in the error
shown above. However, it is not the same case for libclang, which is also
a tool but links only against libLLVM.so.
To fix this problem, add LLVM_DYLIB_COMPONENTS=all.

libclang.so is statically linking against all LLVM static libraries
instead of linking dynamically against libLLVM.so.
This patch fixes this problem by setting LLVM_LINK_LLVM_DYLIB to ON.

This patch provides Clang tools and libraries for the host and
libclang for the target.
host-clang is needed to build libclc, which is provided in a follow-up
patch.
We need libclang for the target because it is used by most of OpenCL
implementations.
A later patch in this series will enable Clover, the OpenCL
implementation part of Mesa3D, which requires libclang.
clang-tblgen must be copied to HOST_DIR as it is not installed by
default but is needed for cross-compilation:
