Finally I was able to fix both X11 and libinput with following steps:
1. Revert epoll-shim. It fixed X11 device driver attachment. (New
version was working for me some time ago. I should check what has
happened recently)
2. Fix its linkage with adding 'LDFLAGS= -pthread -lrt' line to Makefile
3. Remove patch-src_evdev.c.reopen from libinput to fix 'libinput
list-devices' crash (The patch is integrated in to patch-src_evdev.c in
last revision)
4. Restore libinput-record with replacing versionsort with alphasort.
Add '${REINPLACE_CMD} -e 's|versionsort|alphasort|'
${WRKSRC}/tools/libinput-record.c' to post-patch target.
