Yes, I had run into this issue as well.  I had just missed that
permission denied failure in haste and thus my brute force symlink.

The goal is to build a cross toolchain which is stand alone but from
which the libs are copied into the actual target which will boot.  This
is roughly what buildroot does when using an external toolchain (I believe).

In this case, using --disable-shared does not seem reasonable as I'd
like to have shared libs.  I'll take a look at --syslibdir and DESTDIR
and see if they accomplish what I think I want.  The symlink from ld to was my quick work around and produces a system which boots and
runs fine as far as I can tell but which now seems as though it may not
be the best method (besides my symlink command not covering all cases
for the archs used in the CLFS book or supported by musl).
