This commit fixes several issues with linux-fusion so that it builds
properly with the current Buildroot:
* Following the rework of the Linux kernel build process in
Buildroot, a few adaptations were needed: depend on
BR2_LINUX_KERNEL instead of !BR2_KERNEL_none, use
$(LINUX26_VERSION_PROBED) to get the real kernel version, etc.
* Add a LINUX_FUSION_BUILD_CMDS that actually does the build of
linux-fusion.
* Define SYSROOT for linux-fusion to TARGET_DIR so that at target
installation, kernel modules are installed in $(TARGET_DIR)
* Replace the staging installation by a simple one-liner that only
installs the linux fusion header, needed for DirectFB to use the
fusion kernel module
* Fix the uninstallation macros. They have been misunderstood as
hooks, while their are in fact normal macros.
* Add a patch to fix a build failure in linux-fusion itself (missing
<linux/sched.h> include in fusiondev.c)
