Bug#849150: sagemath: FTBFS on arm64 and ppc64el: cannot allocate memory building docs

[Ximin Luo]

Hi, this does not look like a simple out-of-memory, but a bug involving libgomp. A quick Google search of the error message shows that there was some issue involving libgomp, dlopen and GCC years ago, but it's unclear if this is issue here is related.

The error occurs right when the docbuild starts, before it actually attempts to build anything, so my guess is that it would also occur when starting the normal Sage CLI. So I don't think we should skip the docbuild and release the build products as-is.

Given everything else that we need to do, it's unlikely that we'll have time to fix this in a timely manner, unless we get more volunteers on the team. Patches welcome.
