metawarnings is not a proper word, how about just eliding the part in
parentheses?  Yes, I know I'm probably too picky on language; if it
starts bothering you, I'll offer more beer when we should meet.  ;-)

How about s/the explicit ...(\(.*\))/catch-all warning flags \1/
and just naming the test warning-groups-win-over-strictness.test?

double space

I'm not sure it works to put AM_INIT_AUTOMAKE in an included macro.
We definitely have places in autotools somewhere that grep for it,
but I don't know if any of those are relevant here.

$sleep or remove autom4te.cache here.

Likewise here.

You are not using command-line options here.  Is that intended?  If not,
then it seems like the test description does not fully match the action.

trailing white space.

OK with that addressed.
