kbuild: do section mismatch check on full vmlinux
Previously we did do the check on the .o files used to link vmlinux but that failed to find questionable references across the .o files. Create a dedicated vmlinux.o file used only for section mismatch checks that uses the defualt linker script so section does not get renamed. The vmlinux.o may later be used as part of the the final link of vmlinux but for now it is used fo section mismatch only. For a defconfig build this is instant but for an allyesconfig this add two minutes to a full build (that anyways takes ~2 hours). Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
