[GSoC - x86_64] Minimal BSP to review

[Sebastian Huber]

Hello Amaan,

I think it is quite confusing to review the individual commit. I will 
review the final patch set.

Just one thing:

x86_64-rtems5-ld --verbose | head -n 20
GNU ld (GNU Binutils) 2.30
   Supported emulations:
    elf_x86_64
    elf_i386
    elf_iamcu
    elf32_x86_64
    elf_l1om
    elf_k1om
using internal linker script:

OUTPUT_FORMAT("elf64-x86-64", "elf64-x86-64",
               "elf64-x86-64")
OUTPUT_ARCH(i386:x86-64)
ENTRY(_start)
SEARCH_DIR("/build/rtems/5/x86_64-rtems5/lib");

Please add the FSF notice to your file if necessary.
