I've applied, but after completely rewording the commit log. Indeed,
there is a priori no reason why ldconfig should not work when building
for the host. So the argument "let's do like for the target" is not
very good.

However, it turns out that on some machines (including gcc20, where the
build failure occurs), ldconfig must be called as /sbin/ldconfig,
since /sbin is not in the PATH of normal users. And when ldconfig fails
to run, the luajit Makefile does not create the symbolic links. And
since indeed running ldconfig is not really needed for us, passing
LDCONFIG=true is a reasonable workaround.

Thanks!
