toolchain-external: fix rebuild/reinstall for Linaro toolchains
For Linaro toolchains, a special post install staging hook is used to create two symlinks needed for the dynamic loader to find the libraries. However, the way the link is created prevents a 'make toolchain-external-reinstall' from succeeding, because the symlink already exists and points to a directory: ln -sf . /home/thomas/projets/outputs/training/target/lib/arm-linux-gnueabihf ln: '/home/thomas/projets/outputs/training/target/lib/arm-linux-gnueabihf/.': cannot overwrite directory This commit adjust the hook to pass the '-n' option so that the link name is treated as a normal file if it is a symbolic link to a directory.
