From: Vasily Gorbik <gor@xxxxxxxxxxxxx>
commit 46c7405df7de8deb97229eacebcee96d61415f3f upstream.
Currently x86 cross-compilation fails on big endian system with:
x86_64-cross-ld: init/main.o: invalid string offset 488112128 >= 6229 for section `.strtab'
Mark new ELF data in elf_create_undef_symbol() as symbol, so that libelf
does endianness handling correctly.
Fixes: 2f2f7e47f052 ("objtool: Add elf_create_undef_symbol()")
