kbuild: modpost on vmlinux regardless of CONFIG_MODULES
Based on patch from: Magnus Damm <magnus@valinux.co.jp> This has the advantage that all section mismatch checks are run regardless of modules being enabled or not. When running modpost on vmlinux output: MODPOST vmlinux When running modpost on modules output count of modules like this: MODPOST 5 modules Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
