Almost all ebuilds using ./configure support reading EXTRA_ECONF to
pass additional arguments (done automatically through econf wrapper).

e.g. EXTRA_ECONF="--enable-inews" could be added through package.env[1]

Can similarly be done for meson and cmake with MYMESONARGS and
MYCMAKEARGS if the ebuild is using the meson/cmake eclass.
ebuilds with custom systems may sometime use EXTRA_ECONF anyway
or some other custom variable (e.g. EXTRA_FFMPEG_CONF), usually
seen in the ebuild itself.

If you think it's an important option (haven't checked what it's
about), could also fill a bug to get it added / supported for
the long term.
