kbuild: fix ia64 breakage after introducing make -rR
kbuild used $ยค(*F to get filename of target without extension. This was used in several places all over kbuild, but introducing make -rR broke his for all cases where we specified full path to target/prerequsite. It is assumed that make -rR disables old style suffix-rules which is why is suddenly failed. ia64 was impacted by this change because several div* routines in arch/ia64/lib are build using explicit paths and then kbuild failed. Thanks to David Mosberger-Tang <David.Mosberger@acm.org> for an explanation what was the root-cause and for testing on ia64. This patch also fixes two uses of $(*F) in arch/um Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
