Thanks a lot for this valuable hint! I investigated this:

1) LIBRESOLV_SO seems to be not defined. The reason seems to be that
__GNU_LIBRARY__ is not defined and thus gnu/lib-names.h is not included.
(I grepped the code and build-reesults just after the build stage.)

2) Even if LIBRESOLV_SO would be defined, we would need to append the
store path. (No problem, though.)

Any idea how to solve 1)?
