According to Richard Hacker on 1/10/2008 5:39 AM:
| As a hint, make adds 's' to the environment variable MAKEFLAGS:
| MAKEFLAGS=s

| I hope this patch is portable.... I am certainly no expert in portability!
Unfortunately, it is not: read
http://www.gnu.org/software/autoconf/manual/html_node/The-Make-Macro-MAKEFLAGS.html#The-Make-Macro-MAKEFLAGS
That said, parsing MAKEFLAGS is still possible, it is just more complex
than checking for the existence of a single letter s, since long options
may also contain a single letter s. And there are examples of doing so,
such as automake's parsing of MAKEFLAGS to determine if -k is active as
part of its $(RECURSIVE_TARGETS) goal.
