After thinking about this some, there's a good reason why musl doesn't
use a relative path for the symlink, since it's possible to have the
syslibdir be different than the libdir (names taken from musl Makefile).

In this case, the path needs to be a full one.  Likely this means the
book is doing the wrong thing when installing musl or reinstalling musl
after building gcc is the more right thing to do.  Reinstalling,
assuming you don't delete the musl dir after using it, will fix the
issue, you shouldn't need to rebuild then.  But I've not tested this.
