I found the problem: It was the -fPIC option suggested by llvm-config:

$ llvm-config --cflags
-I/usr/lib/llvm-3.0/include -DNDEBUG -D_GNU_SOURCE -D__STDC_CONSTANT_MACROS -D__STDC_FORMAT_MACROS -D__STDC_LIMIT_MACROS -g -O2 -fomit-frame-pointer -fPIC

Without the -fPIC option everything works. However, now I don't know what 
to actually write into the Cflags of llvm.pc.
