I suspect your libx.so.1.0.1 is missing an SONAME.  One should be added to it
that matches the filename of the "real" library.  (It's possible that it has an
soname already, it just doesn't match the filename.)

Once that is done, then the dynamic linker should be able to find it w/o the
libx.so link.

(The links should only ever be used for development.  This is a somewhat common
bug, and a good way to find these problems.)

I'd also suggest we add a sanity check for this condition, so it will be easier
for people to identify in the future.
