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.
