 This is where libiberty should be found...

 ... but instead, it is found in host/usr/lib.

 That's pretty bad, libiberty should not be installed in the host dir. I also
can't find any code that does that (nothing passes --enable-install-libiberty
except the target binutils).

 So can you trace back which step of the build installed libiberty in the host
dir? Perhaps share your defconfig?
