    toplevel.mk: use relative path for feeds/base symlink
    
    Currently, feeds/base is created as an absolute symlink to $(TOPDIR)/package.
    If the OpenWrt source tree is copied to another location for building (while keeping the old tree), the symlink will still point to the package directory in the old tree.
    Using a relative symlink ensures that feeds/base always points to the package directory within the current OpenWrt source tree, improving portability and avoiding incorrect links.
