[Qemu-trivial] [PATCH] configure: Remove unused CONFIG_SIGEV_THREAD_ID switch

[Thomas Huth]

The CONFIG_SIGEV_THREAD_ID switch is unused since the related code
has been removed by commit 6d327171551a12b937c5718073b9848d0274c74d
("aio / timers: Remove alarm timers"), so it can safely be removed
nowadays.
