In fact, I don't, because I now recall why I did that.  It is related
to pluseq7 which fails with this test, and it was it that made me
write this snippet.

Given that `the user is allowed to shoot in her foot', I don't
understand pluseq7:

#! /bin/sh

# Test that `+=' fails when required.

. $srcdir/defs || exit 1

cat >> << 'END'

# If you do this in a real, I will kill you.
cat > << 'END'
lib_LIBRARIES = libq.a
libq_a_SOURCES = q.c
AR += qq

: > q.c

$ACLOCAL || exit 1
$AUTOMAKE && exit 1
exit 0

If we agree the test is wrong, I can apply the aforementioned patch.
It's effect is to _set_ AR to qq (since there is no definition
