If you are not using something like "build.sh -E -D /" you should ignore that
entry.

It would be something like:

	cd src/libexec/ld.elf_so
	${TOOLDIR}/bin/nbmake-${arch} dependall
	${TOOLDIR}/bin/nbmake-${arch} install

Right.

Failed builds how? If you are using "build.sh -u" you may need to manually
clean the object dir for all instances of "binutils" (depending on when
you did the last sucessful build).

A safe way is to completely remove the object dir and build everything from
scratch.
