With sys-fs/udev-204 installed I get:

$ pkg-config --libs --static libudev
-ludev -lrt
$ grep lrt /usr/lib64/pkgconfig/libudev.pc
Libs.private: -lrt

In which the -lrt is the important bit. It's required for clock_gettime.

So either eudev is broken and doesn't contain proper Libs.private: in 
libudev.pc file, or sys-fs/lvm2's build system is broken and doesn't 
query proper Libs.private: from libudev.pc when building lvm2 with static.

For the record. There is no reason to use sys-fs/eudev at this time, it 
doesn't bring anything to the table sys-fs/udev doesn't have. In fact, 
sys-fs/eudev has broken USE="+rule-generator" which leads to random 
interface names.
