Is this a toolchain in the distribution, or an unpatched gcc-4.9.1
which you built yourself?

We have seen countless similar problems in the past, which is why we
recommend using the reference toolchain, which can be built by running:

make crossgcc

in the coreboot source tree. On subsequent make commands, the build
system will autodetect a successfully built reference toolchain and
use that instead of the regular toolchain in the system.
