Ah good idea, I'll look what gentoo does.

I have found out that `uname -m` in i386 containers returns x86_64. If
I do `linux32 ./configure (..flags..)` then everything builds alright
for i386.

Yeah you just need to disable ASLR when building, and for old images
without X toolkit is ok. People are already happy with the amd64
image, I'm just trying to build the same dockerfile to arm64
(https://github.com/Silex/docker-emacs/blob/master/23.4/ubuntu/14.04/bootstrap/dev/Dockerfile).

I'll try your suggestions and report.

Thanks,
