[PATCH] kernel/modsign_certificate.S: use real contents instead of macro GLOBAL()

[Chen Gang <gang.chen@asianux.com>]

For some architectures, tool chain is not smart enough to recognize the
macro with multiple lines (e.g. arc tool chain), and for common ".S"
file, this kind of macro is also rarely used.

So expand the related contents of macro to let it pass compiling (can
use "arc-elf32-objdump -x" to know about it).

The related error (allmodconfig for arc):

    LD      init/built-in.o
  kernel/built-in.o: In function `load_module_signing_keys':
  kernel/modsign_pubkey.c:66: undefined reference to `modsign_certificate_list'
  kernel/modsign_pubkey.c:71: undefined reference to `modsign_certificate_list_end'
  kernel/modsign_pubkey.c:67: undefined reference to `modsign_certificate_list_end'

The related tool chain information:
