-/* Return the unrelocated code address at which execution begins for
-   ABFD, under the 64-bit PowerPC Linux ABI.
-
-   On that system, the ELF header's e_entry field (which is what
-   bfd_get_start_address gives you) is not the address of the actual
-   machine instruction you need to jump to, as it is on almost every
-   other target.  Instead, it's the address of a function descriptor
-   for the start function.  A function descriptor is a structure
-   containing three addresses: the entry point, the TOC pointer for
-   the function, and an environment pointer for the function.  The
-   first field is what we want to return.
-
-   So all we do is find the section containing the start address, read
-   the address-sized word there out of the BFD, and return that.  */
