Creating essential symlinks
Some programs hard-wire paths to programs which don't exist yet. In
order to satisfy these programs, we create a number of symbolic links which
will be replaced by real files throughout the course of this chapter when
we're installing all the software.
ln -s /tools/bin/{bash,pwd,cat,stty} /bin
ln -s /tools/bin/{perl,install} /usr/bin
ln -s /tools/lib/libgcc_s.so.1 /usr/lib
ln -s bash /bin/sh
ln -s ../usr/bin/install /bin
