It looks like the *libc you are using does not enable the
sysenter/sysexit kernel call convention for x86, you may want to pass
--disable-x86-vsyscall to the configure script, then rebuild from scratch.
Also, I would recommend to pass --disable-smp in the same move, since
Xenomai enables SMP support by default for the x86 architecture, and
although this would still work with a UP kernel (the opposite would
not), there is no point on the Geode.
