deps: define missing operator delete functions

Section 3.2 of the C++ standard states that destructor definitions
implicitly "use" operator delete functions. Therefore, these operator
delete functions must be defined even if they are never called by
user code explicitly.
http://www.open-std.org/JTC1/SC22/WG21/docs/cwg_defects.html#261

gcc allows them to remain as empty definitions. However, not all
compilers allow this.

This pull request creates definitions which if ever called, result
in an abort.
