You are right.
The errors were because of version 3.0.7. I didn't realize, that prepare-kernel.sh script doesn't only apply the patch. But it also copies part of the xenomai to the kernel.
 
Meanwhile I tried the latest git (probably master branch). I got another error (simple to fix) in one of the rtnet drivers:
drivers/xenomai/net/drivers/e1000e/netdev.c: In function ‘e1000e_set_interrupt_capability’:
drivers/xenomai/net/drivers/e1000e/netdev.c:1225:11: error: implicit declaration of function ‘pci_enable_msix’; did you mean ‘pci_enable_msi’? [-Werror=implicit-function-declaration]
     err = pci_enable_msix(adapter->pdev,
           ^~~~~~~~~~~~~~~
           pci_enable_msi

 I would not suggest next, master and stable/v3.0.x should do. But
 v3.0.7 and older will not work.
 
 As far as i understood we will soon have a v3.1, for people that like
 their releases ;).
