I think if i execute gcc to get me the final executable

the linker may not be getting correct linker script or the above definitions
such as (hardware_init_hook etc) are not there in the linker script
which ld
is looking for.
Am i correct ?
Yes, you are.
Just look at the ld.info documentation (part of binutils package) to
study how the linker takes your script and which commands you can use to
write this script.
Your command line to compile should look like that (if your linker
script is named "hello.ld"):
m68k-coff-gcc -Wl,--script=hello.ld hello.c
Moreover, as your gcc compiler do not link with a default C standard
library, I think you did not generate and install correctly the newlib
package.
That's why reference to atexit, printf, _exit and _cleanup symbols
are unresolved.
Your gcc compiler should automatically (without adding any option to
the m68k-coff-gcc invocation) link your executable file with the libc.a
or libg.a.
Check the presence of these libraries under:
<your-installation-directory>/m68k-coff/lib
For __FINI_SECTION__ and __INIT_SECTION__ sections, you should have
defined them into your linker script.
For software_init_hook and harware_init_hook symbols, I don't know.

Pierre.
