Dear coreboot folks,
GCC 6 is in Debian Sid/unstable [1] in parallel to the default GCC 5.3. The binary is `/usr/bin/gcc-6`. I’d like to quickly test this with coreboot to see if everything still builds and runs fine.
Running `make HOSTCC=gcc-6 CC=gcc-6` partially works. GCC 6 is used for the utilities, but not for building coreboot.

What variable do I need to set, so that GCC 6 is used for everything?
Thanks,
Paul
PS: I am well aware, that only the coreboot toolchain is officially supported, but I have good experiences with the Debian toolchain on the ASRock E350M1 and Lenovo X60, and it really saves me the time of building the toolchain myself, which takes quite some time on the ASRock E350M1 and Lenovo X60.
