I haven't had much luck convincing the Debian maintainer of this, see
bugs #799036 and #799099.
Julia 0.4.0 has now been released [1] and includes better support for
arm and ppc.
I'll pursue this further once 0.4.0 has been packaged.

In the meantime, I have succeeded in building julia 0.3.11 on armhf by
cherry-picking patches from 0.4.0 and pushing some of my own [2].
The build succeeded on a Jetson TK1 board [3], but currently fails on
my LIME (not LIME2) board with 'g++: internal compiler error: Killed
(program cc1plus)'.

Fortunately, the binary package built on the Jetson installs and runs
on the LIME, see attached screenshot.
I've made the source and binary packages available [4], and those who
only want to experiment with the binary package can try the following:

$ wget http://rrsg.ee.uct.ac.za/julia-arm/julia_0.3.11-1ubuntu2~ppa7_armhf.deb
# apt-get install julia_0.3.11-1ubuntu2~ppa7_armhf.deb
# apt-get install -f
