Try using a linker script instead.  Use "v850-unknown-elf-ld
--verbose" to get a copy of the built-in script, then add memory
regions to it and assign sections to regions as appropriate.

Normally, you would provide an sbrk() for malloc to use.  Look in
src/libgloss for examples of how various CPUs solve these problems.

Normally, you would provide a write() for newlib to use for all that.
