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!
