xenomai: bump to 2.6.1
The largefile patch is no longer necessary, it has been merged upstream. However, in order to make the build work properly with Thumb2 toolchains (such as Linaro toolchains), an additional fix is needed. This fix is already upstream and will be part of upcoming Xenomai releases. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
