bash uses "gethostname()" if it is avaliable, or it's own version (in
oslib.c). you
can delete line "#define HAVE_GETHOSTNAME 1" in config.h and hack this
function
to downcase name.

#if !defined (HAVE_GETHOSTNAME)
#  if defined (HAVE_UNAME)
#    include <sys/utsname.h>
int
gethostname (name, namelen)
     char *name;
     int namelen;
{
  int i;
  struct utsname ut;
  --namelen;
  uname (&ut);
  i = strlen (ut.nodename) + 1;
  strncpy (name, ut.nodename, i < namelen ? i : namelen);
  name[namelen] = '\0';
  return (0);
}
#  else /* !HAVE_UNAME */
int
gethostname (name, namelen)
     int name, namelen;
{
  strncpy (name, "unknown", namelen);
  name[namelen] = '\0';
  return 0;
}
#  endif /* !HAVE_UNAME */
#endif /* !HAVE_GETHOSTNAME */
