LU-6323 build: fix debian to compile with external IB

Problem is that macro O2IBPATHS might be "$LINUX $LINUX/drivers/infiniband".and --with-o2ib will be assigned a two string which will make building hit following failure:

./configure --with-linux-obj=/lib/modules/3.13.0-43-generic/build \
--disable-server \
--disable-quilt \
--disable-dependency-tracking \
--disable-doc \
--disable-utils \
--disable-liblustre \
--disable-iokit \
--disable-snmp \
--disable-tests \
--enable-quota \
--with-o2ib=/lib/modules/3.13.0-43-generic/build /lib/modules/3.13.0-43-generic/build/drivers/infiniband
configure: WARNING: you should use --build, --host, --target
configure: WARNING: invalid host type: /lib/modules/3.13.0-43-generic/build/drivers/infiniband
