Thanks for your patch. Unfortunately there's a reason why this hasn't
been implemented, because it simply doesn't work. Think about the
following scenario:

1. Make a build with BR2_PACKAGE_NTP=y, BR2_PACKAGE_OPENSSL=y

2. Run "make openssl-uninstall"

3. ntp is now broken on the target, because the ntp binary is linked
   against libopenssl.so, but libopenssl.so is no longer on the target

Best regards,

Thomas
