 `libb10-datasrc` does link to the new in-memory datasource library. But
 this forms a part of the program that links to `libb10-datasrc`. I'm not
 sure how missing symbols inside the static DS's `.so` get resolved to
 the ones in the main process without `-rdynamic`.

 This is why I don't know how it's happening.

 Added. :)

 Nod. :)
