Your kernel config says that your x86 CPU does not provide any
time-stamp counter, but the user-space programs ask for it. If the
kernel config is right (i.e. the CPU selection is correct), then you
need to switch off the TSC requirement [which defaults to on] when
configuring the user-space Xenomai support: e.g.

.../configure --disable-x86-tsc

$ make clean install 

README.INSTALL has more on feature selection, and explains why we must
enforce it.
