The database units shipped with FPC have been written against a particular version of the API, and hence should search for those specific library versions that are known to implement that version of the API. Target/host system does not enter the picture in this scenario. That difference is pretty much only relevant if you use the system's C headers because those will correspond to the library version pointed to by the unversioned symbolic link.
