[gentoo-dev] Proposal of accepting arguments to `default` in src_install (and more?) phases in EAPI=5 (for the next council meeting?)

[Samuli Suominen <ssuominen@gentoo.org>]

Example,

- Package is using autotools.
- The default phase like below works for the package:

src_install() {
emake DESTDIR="${D}" install
dodoc README
}

So when writing a new ebuild you would only add:

DOCS="README"

And be done with it. Then the next version of the package needs extra 
argument passed to emake install, for example:

src_install() {
emake DESTDIR="${D}" init_d_path="/usr/share/doc/${PF}/examples" install
dodoc README
}

So you are /forced/ to write entire src_install() while you only want to 
append one argument to emake install.

The current workaround for this is to use EXTRA_EMAKE from ebuild, but I 
find this rather ugly (if not even forbidden by some PMS magic?)

Can we make econf in src_configure, emake in src_compile, and emake 
install in src_install accept arguments "$@" in EAPI=5, please?
