[support/ld] Add linker support for reconfigurable heap.
- common_header.inc: Declare EXTERN symbols _lm_heap_start and
_lm_heap_end.
- common_rom.inc: Check for _lm_heap_start and _lm_heap_end. If they
are defined, preserve their values. Otherwise, _lm_heap_start is
starts after .bss, and _lm_heap_end is the end of SRAM.
This allows existing linker scripts to continue using the old heap
scheme, but allows for customizability elsewhere.
- syscalls.c: Respect the addresses of _lm_heap_start and _lm_heap_end
as the boundaries of the heap in _sbrk().
