[LU-5853] el7 build broken

Related — Tue, 4 Nov 2014 18:16:35 +0000

It looks like a recent landing to master has broken server builds for el7. The only reason this isn't a Blocker is because it's only seen during sever builds, not in client only builds. At the moment we don't routinely do server builds for el7. As soon as we do this problem will be a blocker.

I strongly suspect the problem is due to the recently landed http://review.whamcloud.com/#/c/9299; ~~LU-4647~~ nodemap: add mapping functionality; since the build errors appear in code that's new with this commit. example errors:

I suspect only seen in rhel7 so far as I think it's related to HAVE_ONLY_PROCFS_SEQ #defined by autoconf. If that is true it will also break build on sles12 server too.
