[Buildroot] crosstool/buildroot ldconfig failure in "target-finalize" during build using Fedora 13

Hello,
After upgrading my build machine from Fedora 10 to Fedora 13 it appears
that the host's "ldconfig" command is no longer usable for cross build
application. The build thus fails when it attempts to execute
/sbin/ldconfig during the "target-finalize" stage.
When building using the internal toolchain generated by buildroot, I do
not see an issue. When using an external toolchain such as crosstool-ng
it shows up.
To work around the issue I pulled in the July 26th changeset to the
Makefile to check for and use a $(TARGET_CROSS)ldconfig and then I
modified my copy of crosstool (version 1.7.2) so that it would install
the cross ldconfig along with its cross ldd. That gets me working fine
for uclibc builds.
When I tried a glibc build, there is no cross ldconfig available.
I also notice that in crosstool 1.8.0 the cross ldd is replaced by a
script so the cross ldconfig may not even be available (I don't know for
sure since so far I have only seen the notes in the changelog and
haven't actually tried crosstool 1.8.0 yet).
It appears to me that the assumption an external toolchain will provide
a cross ldconfig is not valid and the assumption that the host ldconfig
is usable as a cross tool in the absence of this is no longer valid.
Since it is the buildroot "target-finalize" that needs a usable ldconfig
I figure it is appropriate to raise this matter here for discussion
first.
Anyone have suggestions as to how best to approach this?
Regards,
Darcy
