When converting ELF64 binary format into efi-app-ia64 format by objcopy
command, optional header magic number in efi-app-ia64 target file is wrong.
Originally its magic is 0x10b, it should be 0x20b.
In Portable Executable and Common Object File Format Specification, it says
that optional header magic number determines whether an image is a PE32 or
PE32+ executable, 0x10b represents PE32 and 0x20b represents PE32+.
On IA64 platform it should be PE32+ image but not PE32 image.
The following is patch for binutils-2.17, elilo package is tested with this
patch on IA64 platform, converted target file elilo bootloader can run in old
EFI bios, and also it can run in new EFI bios.
