The objcopy man-page teaches:
--target=bfdname
Use bfdname as the object format for
both the input and the output file
This implies for --target=efi-app-x86_64 that the input file would have
to be an EFI app.
Objcopy in binutils 2.45 checks this more strictly than previous versions
and refuses to accept an ELF file as input with --target=efi-app-x86_64.
Replace --target by --output-target for building sandbox and x86 EFI
binaries.
