kobject: Always build in kernel/ksysfs.o.
kernel/ksysfs.c seems to be a random dumping group for misc globals that the rest of the tree depend on. This has caused problems with exports in the past when sysfs is disabled, which can already be observed in commit-id 51107301b629640f9ab76fe23bf385e187b9ac29. The latest one is the kernel_kobj usage, which presently results in: fs/built-in.o: In function `debugfs_init': inode.c:(.init.text+0xc34): undefined reference to `kernel_kobj' make: *** [.tmp_vmlinux1] Error 1 kernel/ksysfs.c itself at this point only contains globals and some basic sysfs initialization, the sysfs initialization code is optimized out when we build with sysfs disabled. Given that, it's easier to just build in unconditionally, rather than trying to find some other random place to dump and initialize the globals. Additionally, the current trend seems to be decoupling of kobjects from sysfs, in which case it still makes sense to perform the kernel_kobj initialization that happens here even if sysfs is disabled, as lib/kobject.o is built-in unconditionally.
