[Qemu-devel] [PATCH] ivshmem-server: ivshmem-clean: Install only when eventfd() is available

[Kamil Rytarowski]

Currently ivshmem requires eventfd() which is Linux specific.
Do not and build it unconditionally on every Linux/BSD/Solaris.

This patch indirectly fixes build failure on NetBSD, where these tools
additionally require -lrl for shm_open(3). In future there should be
added support for NetBSD and the linking addressed appropriately.
