tools/elfutils: prevent invalid include of stack binary

In some versions of Xcode, some C++ header has an include
of the standard C++ header "stack" while "." is in the include paths
which can conflict with the binary "stack" built by elfutils.
This leads to a decode error as the binary is interpreted as text.

Add an arbitrary dependency between stack and the C++ program.
