It seems that the issue was not posted soon enough to make it for 1.15.2,
so, here is the patch required for it to work.

I've spotted something extra:
package/efl/efl.mk:312: *** EFL_SITE (http://download.enlightenment.org/rel/libs/efl/) cannot have a trailing slash.  Stop.
Affected packages are:
econnman efl elemines empc enlightenment libcanberra libelementary libemotion-generic-players libetrophy libevas-generic-loaders python-efl rage terminology x11r7
This fixes it:
sed -i 's@\(_SITE = .*\)/$@\1@' $(grep -rl '_SITE = .*/$')

Regards,
  Vicente.
