Seems there's confusion regarding this issue.

There's two issues:
A. bug #778905: pthread / sem_init undefined references
B. bug #790329: error: missing filename after -o

But B was marked a duplicate of A despite different error, then A received a fix while it actually fixed B.

A remains.

To reproduce, need sys-fabric/librdmacm (automagic) and get:
    checking for iSER support... yes

This is already fixed in the upstream git, but upon looking at their build I found some other hidden issues which I fixed in this PR.

Seems to build fine now with 1.19.0-r1 and the 9999 ebuilds.
