AArch64 target does not build from 2.45.90 pre-release tarball

[Nick Clifton]

Hi Guys,

   I have run into a very strange problem with the AArch64 target.  If I
   download the 2.45.90 pre-release tarball[1] and try to build for the
   AArch64 target with --enable-shared, gas fails to build:

     $ binutils-with-gold-2.45.90/configure --target aarch64-linux-gnu --enable-shared
     $ make all-gas
     [...]
     /bin/ld: config/obj-elf-attr.o: in function `obj_attr_v2_record':
     gas/config/obj-elf-attr.c:1060:(.text+0x1022): undefined reference to `bfd_elf_obj_attr_v2_init'
     gas/config/obj-elf-attr.c:1066:(.text+0x104d): undefined reference to `_bfd_obj_attr_v2_find_by_tag'
     gas/config/obj-elf-attr.c:1087:(.text+0x1129): undefined reference to `obj_attr_v2_t_append'
     /bin/ld: config/obj-elf-attr.o: in function `obj_attr_v2_subsection_record':
     gas/config/obj-elf-attr.c:1161:(.text+0x1396): undefined reference to `obj_attr_subsection_v2_t_append'
     gas/config/obj-elf-attr.c:1136:(.text+0x1428): undefined reference to `obj_attr_subsection_v2_t_remove'
     gas/config/obj-elf-attr.c:1138:(.text+0x1445): undefined reference to `obj_attr_subsection_v2_t_append'
     collect2: error: ld returned 1 exit status

   If however I build directly from the 2_46-branch sources, everything is fine.
   Also this problem appears to be specific to the AArch64.  I do not have any
   problems building for x86_64, s390x or ppc64le.

   I am continuing to investigate, but I thought that I should mention it in case
   the problem rings a bell with someone...

Cheers
   Nick
