Please don't!
Who will solve ticket #32768 --
https://trac.sagemath.org/ticket/32768
"centos-7-i386: SIGFPE while building dochtml"
with no other information at all.
My on topic question (given the power of 2 discussion) is:
I'm curious -- what is the situation is with Sage and 32-bit Linux?
I ask this because I recently wanted to build a specific Docker image
involving 32-bit pypy from source
in order to try out pypy,js, and couldn't do it! Support for "32 bit
linux distributions" has been shrunk a lot
in recent years ago (at least what was required by that Dockerfile),
in a way that really surprised me.
There's also an amazing project called v86, which runs 32-bit x86
operating systems entirely in your web
browser your Web Assembly.
https://copy.sh/v86/
(I think this is both amazing and at the same time completely useless
for probably anybody reading this.)
One of the difficulties for them is lack of support for 32-bit Linux
distros. E.g., if you click
https://copy.sh/v86/?profile=archlinux
you're running 32-bit Arch Linux in your web browser nearly instantly,
and it downloads files as needed
when you first reference them. But as they explain
https://github.com/copy/v86/blob/master/docs/archlinux.md
"The last ISO installer version of Archlinux that supports 32-bit is
2017.02.01. Later versions of the archis
os don't work on the v86 emulator because the installer only supports
x86_64, not x86 anymore. For existing
Archlinux installations, updates and patches will be done until
somewhere around 2018."
