Sorry, I'm an idiot; ldconfig is packaged with glibc nowadays, and
probably was never part of BusyBox.  I think you will need ldconfig,
ld.so, and the ld-linux.so.3 symlink from build-glibc/elf, in addition
to the various .so's and .so.[1-9]'s from build-gcc and build-glibc.
ld.so needs the cache and symlinks that ldconfig creates based on the
instructions in /etc/ld.so.conf.  (I usually build initrds using
Debian mechanisms, so I'm a little hazy on what absolutely has to be
in there; Debian initrds usually have a shell script as /sbin/init,
which does various modprobes and mounts and then pivots onto the real
root and invokes the real init.)

Note that ldconfig doesn't have to be in the initrd, but it has to be
run on the contents of the initrd to create ld.so.cache.  (I think.)
I'll be more precise about this once I've redone the initrd mess here;
it looks like ldconfig gets run on our initrd contents only as a side
effect of installing other libraries, and ptxdist (as of the old
version we used previously) doesn't run it explicitly.  Can any actual
experts comment hre?

Cheers,
