zephyr: Bring no_libgcc back to v2.7
no_libgcc support was removed in upstream Zephyr OS, and we still
depend on it to make coreboot-sdk work, as well as to add EC software
panic handling for divide by zero.
This hack emulates how no_libgcc used to function by removing -lgcc
from the linker flags if no_libgcc is set.
