Probably nobody has really used static linking for libdw before. We wouldn't recommend it.
Since the library has no way to know where you're installing a program you link it into, the $ORIGIN methods are not really viable. Resorting to an absolute file name in the library would be dismal.
The library tries the unadorned DSO name if the $ORIGIN name fails. So you can just build your program with an appropriate DT_RUNPATH, as we do for libdw.so itself (see libdw/Makefile.am).
