I build Aurélien's branch inside a zone, but it fails for me with:

error: could not exec the linker `/usr/gcc/6/bin/gcc`: Not enough space 
(os error 12)

For full log, see

I am quite sure that I have plenty of disk space available:

$ df -h .
Filesystem             Size   Used  Available Capacity  Mounted on
rpool/zones/build/build-userland/ROOT/zbe-125
                        114G  14.7G      74.9G    17%    /

Any idea what the problem might be? I build it on Lenovo X220 (4 cores, 
6 GB of memory + 3 GB of swap), OS is updated to latest packages. I 
don't think I limited the zone in any way when I created it.

Thanks,
