kbuild: properly pass options to hostcc when doing make O=..
This fix a longstanding bug where proper options was not passed to hostcc in case of a make O=.. build. This bug showed up in (not yet merged) klibc, and is not known to have any counterpart in-kernel. Fixed by moving the flags macro to Kbuild.include so it can be used by both Makefile.lib and Makefile.host. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
