New review comment by Duncaen on void-packages repository

Comment:
libclang and libclang-cpp are "embedded" compilers, they need those headers. As example the `include-what-you-use` just uses libclang to parse c files and won't work without those headers.
There might be users who just use `include-what-you-use` without clang binaries.
