  Since commit 3f2bdd0701de4f2bca7e6d96f96972e7bcabdd93 (by Yann, in Cc), it is 
necessary to twice-quote the arguments to wget (and wget only). So

PYTHON_KOALA_DL_OPTS = --header "'Authorization: token MY_TOKEN'"

  Yann, I honestly don't understand why this eval is needed, instead of simply 
passing BR2_HG unquoted... But I didn't look too deeply into it.

  Regards,
  Arnout
