package/xenomai: disable cobalt for armv8
When a armv8 target is used in 32bits mode, xenomai fail to detect the ARM architecture and abord the build. (__ARM_ARCH_7A__ is not defined for armv8 cpus). There are no autobuilder failures for this issue since cobalt is never selected, but the following defconfig: BR2_arm=y BR2_cortex_a53=y BR2_ARM_FPU_NEON_VFPV4=y BR2_TOOLCHAIN_EXTERNAL=y BR2_PACKAGE_XENOMAI=y BR2_PACKAGE_XENOMAI_COBALT=y This was initialy reproduced using the raspberrypi3_defconfig with Xenomai package with cobalt selected. In order to use Xenomai on raspberrypi3 in 32 bits mode, one has to select BR2_cortex_a7 instead of BR2_cortex_a53 (see a13a388dd444).
