[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.
