Odd warning about `customize-variable'

[Lars Ingebrigtsen]

I don't know when this started, but I'm seeing one oddball warning when
building Emacs now:

In end of data:
org/org.el:15523:6: Warning: the function `customize-variable' might not be 
defined at runtime.

This is odd, because loaddefs has:

(defalias 'customize-variable 'customize-option)
(autoload 'customize-option "cus-edit" "\

So that alias (and that function it points to) should always be defined.

Anybody know what might be going on?
