Your analysis is correct.  solib.c won't compile on anything but native
systems.
While there is nothing technical stopping it from working - WRS have
relocatable executables (using some WRS specific patches) and _I_think_
the wince (1) target also support a form of dynamic library.

Perhaps one of the people that worked on WinCE can expand/confirm this.
