Errr... There is absolutely no way user-space code can be dynamically
linked with kernel functions. The interface between the two is the
system calls interface.

This is user-space stuff, so it is not related to Kconfig.

As explained in the README.INSTALL file, the sources for the kernel-part
are located in the subdirectories of the ksrc directory, while the
sources for the user-space part are located in the subdirectories of the
src directory.

Anyway, all this comes from the libxenomai library. As witnessed by
people installing and using Xenomai on ARM while following the
installation instructions in README.INSTALL, everything is fine with
Xenomai, your problem is elsewhere.
