MIPS elf64 selection bug

[Carl van Schaik]

There is a bug in the gas code that tests if 64-bit elf is supported.
Still present in the latest CVS

in file:
gas/config/tc-mips.c



function:
static int support_64bit_objects(void)

should be:
---------------
static int support_64bit_objects(void)
{
  const char **list, **l;
  int res;

  list = bfd_target_list ();
  for (l = list; *l != NULL; l++)
#ifdef TE_TMIPS
    /* This is traditional mips */
    if (strcmp (*l, "elf64-tradbigmips") == 0
        || strcmp (*l, "elf64-tradlittlemips") == 0)
#else
    if (strcmp (*l, "elf64-bigmips") == 0
        || strcmp (*l, "elf64-littlemips") == 0)
#endif
      break;
  res = (*l != NULL);
  free (list);
  return res;
}
------------------

The problem was that the original
return (*l != NULL) after the free(list) failed in some cases, returning
NULL
The solution is trivial
