[oe] recipe simplification questions

[Frans Meulenbroeks]

Hi

While browsing through a recipe I stumbled upon the following two functions:

inherit autotools

do_configure() {
        oe_runconf
}

do_install() {
        make install DESTDIR=${D}
}

Two questions:

1) does a  do_configure like above have any use?
I would expect it to be the default case in case of autotools

2) the make install line I have seen on several places.
Isn't it more elegant/simpler to just say
EXTRA_OEMAKE = "DESTDIR=${D}" and remove the whole do_install function?
