It is possible to provide an implementation of the IBinaryParser extension/interface
with addr2line, objdump, nm, ar and file.

Elf.java should be change to make this possible, maybe by making
more methods "protected" or adding new methods say:

Elf.setAddr2line (IAddr2line addr2line);

Then  the default implementation is good enough for your case and we should
think of a way to extend Elf.java, maybe something like.

public class TensilicaElf extends Elf {
	public String getAddr2line () {
		// return the righ path of the addr2line
		// it should be in the PATH.
		return "tensilica-addr2line"
	}
}
