Now that you write down the semantic of the variable, I don't like it
anymore: setting to a non-empty value is clearly not what Buildroot
normally does for boolean variables. We use a YES/NO value.

So instead of this, could we change pkg-rebar.mk to do this:


$(2)_POST_PATCH_HOOKS += remove-rebar-config-dependencies

And then the document should say that the accepted values are "YES" and
"NO" and that the infrastructure defaults to "NO".

Could you have a look at doing this ?

Thanks a lot!
