You're assuming the vendor supplied script will pick up the script
in /compat/linux.  That, is not the case for the Portland Group
script:

if test -x /usr/bin/uname ; then
        uname=/usr/bin/uname
elif test -x /bin/uname ; then
        uname=/bin/uname
else
        # Never seen it anywhere but /bin or /usr/bin, so hopefully it's
        # in $PATH already.
        type uname > /dev/null 2>&1
        if test $? -ne 0 ; then
                echo "install: uname not found in \$PATH environment variable"
                quit
        else
                uname=uname
        fi
fi
