Fixes make test errors with clang compiler on aarch64

(VAPI_*BIN).d targets didnt have fake.api.vapi.h* as dependencies
this causes the compilation to proceed before the python script
generates the header files.
Explicit linking of stdc++ is required for clang as errors like
undefined reference to 'new operator' pop up.
