Fix integration bugs (vboot side)

BUG=chromium-os:8621
TEST=See below

1. Build and run tests of vboot (including linktest)
$ make && make runtests

2. Check if *_stub.o are not in vboot_fw.a
$ nm /build/<board>/usr/lib/vboot_fw.a | grep _stub.o

3. Build and boot x86-generic image
$ ./build_packages --board=x86-generic && ./build_image --board=x86-generic
(Then successfully boot the image you just built)

See CL=4372001 for u-boot side changes
