Is compilation on 32 bit supported?

Description

Tried compiling mxnet using gcc 7.2.0 (32-bit), build fails with 'out of memory error'

Build info (Required if built from source)

Compiler (gcc/clang/mingw/visual studio): gcc

MXNet commit hash: Using tag: 1.0.0

Build config:
After applying the patches at #9273

export MKLROOT="<path-to-full-mkl-32-bit>"

What have you tried to solve it?

1. May not be relevant, but tried passing -ftrack-macro-expansion=0 to CFLAGS.

I was having trouble with windows 32bit and I found defining this
-DDMLC_CXX11_THREAD_LOCAL=0
seems to fix it (but it does generate warnings about not being suported), not sure if it stems from the same problem though.
