This flag begins with double-dashes. Double-dashes introduce a long
option, so make considers the entire text to be a single option; that
is, make parses this as one option "--ignore-errorsuuzzz".
This is the standard parsing for long options in GNU programs.
The other example begin with a single dash; a single dash introduces a
string consisting of one or more single-letter options, so make
interprets it as "-i -g -n -o -e -e -r -r -o -r -s -u -u -z -z -z".
This is the POSIX standard method of parsing options.
