[LU-7019] Lustre client build fails when ./configure called with --with-o2ib=no

Until Lustre 2.8 stable is ready, I've been trying to get the current Git pull to build the client on my Ubuntu machines currently running 3.4.61 every few weeks and there has been a persistent error that causes the build to fail. I've used the same Git pull, or earlier versions of same, to successfully build the server on CentOS 7, but I'm having trouble just getting the client portion built on Ubuntu.

For the client, I'm attempting to build Lustre on the same machine on which I built the Linux 3.4.61 kernel all the Ubuntu machines here are running, so all kernel source, intermediate object, headers, etc. should be available.

The process I'm following is very simple, following something outlined in the old bug report ~~LU-1706~~ where someone else was trying to make Debian packages of the client:

git clone git://git.hpdd.intel.com/fs/lustre-release.git
cd lustre-release
sh autogen.sh
./configure --disable-server --with-o2ib=no --with-linux=/usr/src/linux --with-linux-obj=/usr/src/linux
make debs

We don't use Infiniband here; it's all 10 Gigabit Ethernet, so we don't have an Infiniband stack installed; we don't need one and certainly don't want one!

On CentOS 7 where the server built successfully, we never (knowingly) installed any Infiniband-related packages. I suspect this issue only arises when attempting to build the client portion, or it's in "make debs".

The build process will attempt to roll along and seems to successfully build userland and some other *.deb packages but I never get a kernel module out for the client. The build fails with the error:

configure: error: bad --with-o2ib path

This seems to correspond to, a little earlier up in the build process:

Doesn't seem possible to only build modules...
./configure --with-linux=/usr/src/linux-3.4.61 \
--with-linux-obj=/usr/src/linux-3.4.61 \
--disable-server \
--disable-quilt \
--disable-dependency-tracking \
--disable-doc \
--disable-utils \
--disable-iokit \
--disable-snmp \
--disable-tests \
--enable-quota \
--with-o2ib=

I've actually gone and edited that Makefile and even if I completely remove the "--with-o2ib" flag, it still fails to compile; I believe it hangs up on a similar error elsewhere.

I've tried the hpdd-discuss list and it doesn't seem like the problem has been noticed or fixed by happenstance (I've been trying a different Git pull every few weeks for the last month or two) so I'm hoping a bug report might help.

I've attached the full buildlog from the attempt for review. Just let me know if there's any further information I can provide, or anything else I can try; I'd be happy to give it a try and report back. Thanks.
