nds32_elf_get_relocated_section_contents

nds32_elf_get_relocated_section_contents

nds32_elf_get_relocated_section_contents uses nds32_get_section_contents
to read sections contents, but nds32_get_section_contents has the wrong
behaviour as it calls bfd_malloc_and_get_section.  That function always
mallocs its output buffer, whereas get_relocated_section_contents must
support an already allocated buffer.
