The earlier logfile seems to tell your newbie-mistake :
configure:11134: checking for as
configure:11167: result: no
configure:11245: checking for m68k-elf-as
configure:11275: result: no
So the answer to your second question is that of course you must first
build GNU
binutils, including 'as', which will understand the m68k architecture,
not only
the host x86_64 CPU architecture!
Yes, I'm definitely making newbie mistakes!
Now, I've built the m68k-elf bintools and the cross gcc build gets a lot
further. However, know it gets stuck in libssp, details below.
I'm thinking that its not picking up the right header files.
