Description: Don't use asort() and asorti() awk functions
 BusyBox awk doesn't define them and they aren't necessary for simple array
 iteration.
 .
 Also, fix some newlines in errlist-compat.awk.  POSIX.1-2008 states, "a
 <newline> shall not occur within a string constant."  GNU Awk allows newlines
 in strings and allows them to be escaped.  BusyBox awk also allows newlines in
 strings, but it ignores any preceeding backslash.
 .
 As a result, in BusyBox awk, erroneous newlines are added to errlist-compat.c,
 including in the string in the link_warning macro.  This causes the following
 warnings and errors:
 .
