In short, I used the -m68000 gcc switch and set the following options:

uClibc .config:
TARGET_ARCH="m68k"
# UCLIBC_FORMAT_FLAT is not set
UCLIBC_FORMAT_FLAT_SEP_DATA=y
# UCLIBC_FORMAT_SHARED_FLAT is not set

busybox .config:
CONFIG_STATIC=y
# CONFIG_PIE is not set
CONFIG_NOMMU=y


The full details can be found under:

In the tarball, you can there is a script that should include all steps,
including the ./configure options, as well as all .config's.

It happens after run_init_process() is called.

Thanks!
