I mistakenly assumed that all bfd_targets would be defined on all platforms.
The attached patch to configure.in adds the suggested checks for
bfd_elf64_powerpc[le]_vec into the config test program.

I had tested earlier patches on PPC64 machines with and without current
gcc/binutils, as well as on an x86 box with RHEL 3.  I did some digging and
came up with an x86 box that had RHEL 4 installed, so I tested this current
patch there, too, and it seems OK.
