Bummer - this is creating the hard link that I expected, but is still 
letting me fail 'make check' with:

nbdkit: error: cannot open plugin 
'/home/eblake/nbdkit/plugins/eval/.libs/nbdkit-eval-plugin.so': 
/home/eblake/nbdkit/plugins/eval/.libs/nbdkit-eval-plugin.so: undefined 
symbol: sh_get_ready

so I'm trying to figure out what to put in v2
