if I recompose the failure line and add -m64 it completes. Am I doing something
wrong or is there something wrong with the code? Can someone guide me on a
proper fix for this?

Just a guess, but I bet that if you add a '-dryrun' option to
your CC line, you'll see that the compiler is adding one or
more 32-bit objects at the head of the command line that it
feeds to the linker.
The linker decides what type of object it's building based on the
first object on the command line, so if I'm right about the above,
then that 32-bit object is going to cause ld to complain when it
encounters your 64-bit objects.
The right fix is to tell the compiler to produce a 64-bit object
with -m64 as you've done.
