tenzap 84f245badb Enable "-fsized-deallocation" iif deallocation functions are present ...

On some systems, although "-fsized-deallocation" compiler flag is there,
compilation will fail because some deallocation functions are missing.
Typically 'operator delete ( void* ptr, std::size_t sz )' is missing on some
macOS systems.

This will check their presence.

On macOS we can have this case when using a compiler that supports the flag,
while the OS doesn't have all the deallocation functions. Typically,
::operator delete(ptr, size) appeared in macOS 10.12

Reported error was:
error: call to unavailable function 'operator delete': introduced in macOS 10.12
