Hi,

This looks very wrong. elf_osabi identifies the kernel, not userland. This
commit broke elf32-i386-freebsd and elf64-x86-64-freebsd targets.

As you can see in the definition of those targets (in bfd/elf64-x86-64.c),
elf_osabi field is reset to ELFOSABI_FREEBSD. This is because the kernel of
FreeBSD uses osabi to identify the syscall ABI in loaded executables.

Because of this both FreeBSD and GNU/kFreeBSD have to use this tag. The way you
just redefined it to imply userland rather than kernel leaves GNU/kFreeBSD out
in the cold. Now we're going to hit trouble every time someone uses
ELFOSABI_GNU to check for a GNU feature, and it begins right now with
STT_GNU_IFUNC.

Please, can you reconsider this? There were already ways to check for userland
(ELF Notes). There's no need to redefine existing interfaces to archieve that.
