Docs are being built during 'make check'?

[Jeffrey Walton]

This is weird... Docs are being built during make check. I have to
include MAKEINFO and HELP2MAN in the make check recipe.

My driver scripts looks like:

echo "**********************"
echo "Testing package"
echo "**********************"

MAKE_FLAGS=("check" "V=1" "MAKEINFO=true" "HELP2MAN=true")
if ! "$MAKE" "${MAKE_FLAGS[@]}"
then
    echo "**********************"
    echo "Failed to test Bison"
    echo "**********************"
    exit 1
fi

But the result is:

...

It is very unusual.
