A second version of the i686 meltdown patches were posted this week.
https://lkml.org/lkml/2018/3/5/173 - I guess in a few weeks a later
version will get into Linus's tree and then into the maintained
kernels.

For Spectre, I think the amelioration is already in the stable
trees, certainly it's in 4.9 and I think it will work on i686, with
gcc-7.3 for the full mitigation.  But I agree meltdown is the bigger
problem.

But no, building on most i686 machines became painful years ago
(for typical home users, the memory was small and, by current
standards, slow).  Today, x86_64 with less than 8GB can be painful
when building some packages.
