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

[Aaron M. Ucko]

Source: sagemath
Version: 7.4-3
Severity: important
Justification: fails to build from source

The automatic builds of sagemath for arm64 and ppc64el both ran out of
memory when trying to build documentation:

  [dochtml] ImportError: /usr/lib/«ARCH»/libgomp.so.1: cannot allocate memory in static TLS block
  Makefile:1059: recipe for target 'doc-html' failed
  make[4]: *** [doc-html] Error 1

Could you please take a look?  Since this documentation presumably
winds up in an architecture-independent binary package, perhaps you
can arrange for binary-only builds to skip building it.

Thanks!
