[Buildroot] [PATCH] package/qt5tools: hide qdoc with llvm dependencies

From: "Yann E. MORIN" <yann.morin at orange.com>

Building qdoc requires a llvm and clang for the host.

However, there is a limitation in the llvm and clang packages in
Buildroot, which makes it impossible to havea  host variant without
a target variant.

So, propagate the dependencies of the target llvm and clang, to ensure
we can only have a host-llvm and -clang packages that are correctly

Note that we do propagate all of the dependencies (instead of just the
architecture part), to be consistent.
