[PATCH] uml kbuild: avoid useless rebuilds
- Fix some problems with usage of $(targets) (sometimes missing, sometimes used badly) that trigger partial rebuilds when doing a rebuild. - At that purpose, also factor out some common code for symlinks creation. - Fix a x86-64 build warning, caused by -L/usr/lib, which is anyway useless, and invalid in the x86-64 case. Tested on x86_64 and x86. Signed-off-by: Paolo 'Blaisorblade' Giarrusso <blaisorblade@yahoo.it> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
