+Subject: [PATCH] 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.
