If the linker doesn't follow Y's link to Z, how is it supposed to
resolve Z references?  so yes, you do have to link X with Z -- that's
what explicit linking requires.

Following indirect links (like your Y -> Z) example is the original ld
behavior.  The latest binutils linkers don't do this be default.  You
either had to pass a flag to change how it's built during configuration
(or maybe patch the linker, not sure) to restore the original behavior.
