  That CC= looks bogus to me.  IIUC, you're setting the build (native)
compiler there, not the host (cross) compiler.  configure ought to be
perfectly capable of finding ppc-eabi-gcc itself, it knows to look for it
because you specified --host.  If something went wrong, you would set
CC_FOR_TARGET, but it's best to left configure work things out for itself
unless you really have to, it'll generally set CC and CC_FOR_TARGET correctly.

  Configure thinks you're building on the native system, and hence not
cross-compiling at all.

  No wonder it got confused trying to run a target executable on your build
machine.

 Try not claiming that the build host is ppc-eabi then!
