[ovs-dev] [PATCH] create dir if not exist

[rongqing.li at windriver.com]

From: Roy Li <rongqing.li at windriver.com>

If build dir is not same as the source code, make the target .in wrong
due to no dir:
	vswitchd/ovs-vswitchd.conf.db.5.tmp: No such file or directory

The target .in has not dependency, but in fact, it needs other target to
create the dir to put its result, like builddir/vswitchd in below:

/usr/bin/perl soexpand.pl < ${S}/vswitchd/ovs-vswitchd.8.in | \
    sed \
        -e 's,[@]PKIDIR[@],/var/lib/openvswitch/pki,g' \
           ......
            > vswitchd/ovs-vswitchd.8.tmp

fix it by creating the dir in .in target
