Fix build problems on hurd-i386

Forwarded: partially
Last-Update: 2018-10-24

This patch allows Open MPI to build on Debian GNU/HURD.

Also, the memory:linux MCA component is disabled, since its use of POSIX API
in malloc hooks called very early at startup causes troubles.

Also changes by Samuel Thibault <sthibault@debian.org>
