Yes, try understanding why the Xenomai tools and libraries do build fine in
FDPIC mode by looking at the compilation output. If this is still not enough,
please have a look at the Blackfin Wiki first to get familiar with the Blackfin
toolchain: http://docs.blackfin.uclinux.org/doku.php, and possibly direct your
questions regarding those aspects to one of the available Blackfin forums.
