After some fight I was successful with

$ python ../llvm/utils/lit/lit.py -sv --no-progress-bar --param=llvm_site_config=test/lit.site.cfg --param=build_config= ../llvm/test/Bitcode/null-type.ll

(for LLVM)

$ python ../llvm/utils/lit/lit.py -sv --no-progress-bar --param=llvm_site_config=test/lit.site.cfg --param=build_config= --param=clang_site_config=tools/clang/test/lit.site.cfg ../llvm/tools/clang/test/Sema/annotate.c

(for Clang)

The commands are executed from the root of the build directory. The
build directory is at the same level as the sources:

llvm/
build/
