EmulatorPkg/Unix/Host: Add GCC5 CC/DLINK commands (for GCC >= 5)

These flags are based on the flags from the GCC5 toolchain in
tools_def.template. Since the GCC5 toolchain uses link-time
optimizations (LTO), we must compile and link the 'Host' files with
LTO enabled so we can link to other modules.
