You should also modify the mlt_* files for your target.

There is no stack section or heap section. Stacks are in the bss. As
for the heap the linker script defines a symbol __heap1 which is the
start of the heap and it then extends up to the end of the memory.
A map file is not generated by default. Just add the appropriate flag
to the link command. Or see if objdump will produce enough information
for you.
