I've had to change two things to make cross-gcc happy with this:
1. Change the location of the sysroot. /usr/%{target} is not the
right place to put the sysroot, as binutils/gcc use it to store
target-specific binaries, etc. (binutils stores things like 'as'
in /usr/%{target}/bin, which gcc expects to find there.)
If you use the default sysroot path (i.e. --with-sysroot=yes), the
sysroot gets put in /usr/%{target}/sys-root. That seems like a
sane default to me.
2. Do package /usr/%{target}, as the subsequently built gcc depends
on (see #1) having 'as' in /usr/%{target}/bin and such.
Here's a new version (beware: against a locally modified tree)
with these changes. Seems to work OK for me.
