I reopened a bug about this issue the upstream fix is not enough. See
https://phab.enlightenment.org/T2718
So, for the moment we can build efl 1.15 only with Lua 5.1 (Lua 5.1 was the
default version used at the time I tested the efl bump series).

I have a local branch that bump the efl to the latest version (1.17.0) and the
support for lua-old doesn't build with (5.1, 5.2 and 5.3) due to this issue. The
only solution is to add lua-jit support which build and work correctly (tested
with Qemu).

The problem for 2016.02 is it's too late to enable lua-jit support in efl. So
people using efl with 2016.02 will have to switch to lua-jit when efl will be
updated to a newer version :-/

Do you want me to send a small series (3 patches) adding lua-jit support for
2016.02 ?

Or this one http://patchwork.ozlabs.org/patch/572150/ even if I don't like to
use sed all over the gdb tree :-/

Technically, it's a toolchain issue with gcc 4.9. So if we rebuild a new nios2
toolchain with gcc 5.3 this error is gone. Otherwise we can add an autobuilder
exception for br-nios2-full-2015.11-rc1-71-g90d1299.tar.bz2.

Even we can remove BR2_TOOLCHAIN_EXTERNAL_CODESOURCERY_NIOSII since the new
codesourcery toolchain use gcc 5.2.

We need to rebuild a nios2 toolchain with the upstream patch applied [1] and
disable for BR2_TOOLCHAIN_EXTERNAL_CODESOURCERY_NIOSII:

Otherwise we can apply this one: http://patchwork.ozlabs.org/patch/561414/
