mcs814x: enable POSIX file locking

opkg (and possible other tools) are currently broken as it requires
file locking support enabled in the kernel.
Without this results in a message like:

root@OpenWrt:/etc/config# opkg update
Collected errors:
 * opkg_conf_load: Could not lock /var/lock/opkg.lock: Permission denied.

With this patch opkg is fully functional on this platform.

x86: Fix CONFIG_X86_GRUB_SERIAL=""

With

    .config:CONFIG_X86_GRUB_SERIAL=""

which (AFAICT) is the way to tell GRUB not to use a serial console, in

    target/linux/x86/image/Makefile:ifneq ($(CONFIG_X86_GRUB_SERIAL),)

$(CONFIG_X86_GRUB_SERIAL) expands to `""' (a literal double double-quote),
making the condition unconditionally false.

This patch fixes the situation by passing CONFIG_X86_GRUB_SERIAL through
qstrip before testing.
