kbuild: improve check-symlink
o if include/asm point to a nonexisting directory remove the asm symlink o if include/asm is a directory error out This fixes a situation where one could be left with a symlink to asm-x86 but that directory no longer exist and thus the build would error out. include/asm may be a directory if the kernel tree has been copied Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
