the way clang invokes ld is really weird because neither -dynamic-linker
nor -Wl,-dynamic-linker override the option clang invokes ld, it is only
appended to a command line. using ld explicitly works perfectly even
without need for libclang when linking dynamically, at least for hello
world. unfortunatelly ubuntu does not provide libclang.a in packages and
i don't want to recompile clang itself, so i can't test static build
right now, but it is good that at least dynamic linking works.
thanks for your help!
