gcc-cross-canadian: Add symlink to real-ld alongside other symlinks

In some cases such as cross architecture configurations (using mips-X-linux
on mips64-X-linux), gcc can get confused about finding a 'real' version
of ld. Adding a symlink to 'real-ld' allowed these configurations
to work properly.
