I think this series gives a more complete solution to the problem:

https://patchwork.ozlabs.org/project/qemu-devel/list/?series=3985
  [1/3] linux-user: fix TARGET_SO_LINGER for sparc
  [2/3] linux-user: add SO_LINGER to setsockopt
  [3/3] linux-user: add SO_LINGER to getsockopt

but it needs some updates.

Thanks,
Laurent
