- Removed unnecessary dependency of "$(my_symlink) : $(LOCAL_INSTALLED_MODULE)" We can generate symlink to nonexistent file. Actually in multilib build $(LOCAL_INSTALLED_MODULE) points to file that may not be the target file of the symlink and leads to always obsolete $(my_symlink) in the above dependnecy. - Touch by-product in the dummy rule, to make sure the by-product is newer than the main-product.
