Sergei Trofimovich 2cc0b085fb gnuefi: preserve .gnu.hash sections (unbreaks elilo on IA-64)
Gentoo has slightly modified linker defaults: --hash-style=gnu
This means all ELF files in system have '.gnu.hash' section
but no '.hash' section.

gnuefi's ldscript did not account for it and as a result
one symbol 'ImageBase' did not resolve locally for elilo.so
and caused 'elilo' to fail to load by ia64 EFI:
  Loading.: Gentoo (try new elilo)
  ImageAddress: pointer is outside of image
  ImageAddress: pointer is outside of image

Those two relocations come from crt0-efi-ia64.S PE32 entry point
fdescr:

```
    #define IMAGE_REL_BASED_DIR64<->10
    .section .reloc, "a"
    data4   _start_plabel // Page RVA
    data4   12            // Block Size (2*4+2*2)
    data2   (IMAGE_REL_BASED_DIR64<<12) +  0 // reloc for plabel's entry point
    data2   (IMAGE_REL_BASED_DIR64<<12) +  8 // reloc for plabel's global pointer
```

These refer ImageBase.

The change adds '.gnu.hash' collection (follows existing '.hash'
collection).

Tested on IA-64 by successfully booting elilo-3.16.
