If you don't need the RDMA feature, you could always just --disable-rdma
for now to see if you can get QEMU to build.

Looks like one of your libraries is outdated, for me
'IBV_LINK_LAYER_INFINIBAND' is defined in
/usr/include/infiniband/verbs.h; provided by
libibverbs-devel-1.1.8-3.fc22.x86_64.

Maybe your libibverbs is too old.
