[Buildroot] [PATCH] vim: install /bin/vi as a relative symlink

[Carlos Santos <casantos@datacom.com.br>]

Prevent creating a dangling symlink when vim is not present on the host
machine. With BR2_ROOTFS_MERGED_USR, just link to "vim", since they are
on the same directory, otherwise link to "../usr/bin/vim".
