Add xenomai real-time Framework to buildroot
[Fixes by Thomas, including comments from Arnout:
* Use AUTOTARGETS instead of GENTARGETS
* Use $(KERNEL_ARCH) instead of $(BR2_ARCH) as argument to the
prepare-kernel.sh script. This allows the arch name to be fixed
with the usual sed expressions and the quotes to be stripped.
* Add the --verbose option to prepare-kernel.sh. This allows to get
some clear error message when no Xenomai patch has been found for
the current kernel version.
* Improve the help texts as suggested by Arnout, and remove the
now useless README file.
* Add a BR2_PACKAGE_XENOMAI_SMP option, instead of poking inside the
kernel configuration to find out whether SMP is enabled or
not. This cannot work because: 1) the kernel might be built
outside of Buildroot and 2) if the kernel is built inside
Buildroot, it is built *after* Xenomai, so the kernel
configuration file is typically not yet present.
* Simplify the ARM subarchitecture selection as suggested by Arnout.
* Remove the documentation and development files according to
Buildroot standards (using BR2_HAVE_DOCUMENTATION and
BR2_HAVE_DEVFILES).
* Simplify the /etc/ld.so.conf modification logic.
