With no environment overrides of LD_LIBRARY_PATH or similar, the test cases
in the build tree are expected to find the OpenSSL libraries in the install
target location (if on the default system search path) or when you compile
with "-R", "-rpath" or similar.  So the output of ldd is not surprising.

The tests run with LD_LIBRARY_PATH settings via util/

The test cases exercise the code the same way it is going to be used.
You can do a "no-shared" build if you like, but then some features
that depend on dynamic linking/loading may not be available.  If you're
just trying to bisect a problem, that may be acceptable...
