user error. this is expected behavior: the libs under /usr/$CHOST/$CTARGET/lib/ are libraries that will be linked for $CHOST binaries but used to debug $CTARGET code. libiberty is a bad example as it generally doesn't have any target info in it, so let's use libbfd.a as an example instead. linking against /usr/$CHOST/$CTARGET/lib/libbfd.a will let you run code on $CHOST but load ELFs that are compiled for $CTARGET. if you want to build oprofile for $CTARGET, you need to build binutils for $CTARGET (CHOST==CTARGET). -mike
