Fix build failure: LINK openbios-unix libopenbios.a(load.o)(.text+0xe0): In function `load': ../libopenbios/load.c:58: undefined reference to `elf_boot_notes' libopenbios.a(load.o)(.text+0xe8):../libopenbios/load.c:58: undefined reference to `elf_boot_notes' Move elf_boot_notes variable to load.c to make it also available on Unix build. Also fix a spurious sys_info variable definition.
