 In the old world (as the surrounding comment in makefile says), there
 was the /usr/libexec/ld-elf.so.1 binary which is now a symlink to
 /libexec/ld-elf.so.1. To symlink, we need to make sure that the
 _target_ (and the target is /usr/libexec/ld-elf.so.1) doesn't have
 "schg" flag set. A real solution is to protect the chflags call only if
 target exists, like we do in usr.bin/tip/tip/Makefile.
