Since mgorny is working on compatibility with multilib-portage I
stripped all of the related code.

So this should be the final version. If there are no objections I would
like to commit.

# @BLURB: wrapper for multilib builds providing convenient multilib_src_* functions
# @DESCRIPTION:
#
# src_configure, src_compile, src_test and src_install are exported
# use multilib_src_* instead of src_* which runs this phase for
# all enabled ABIs
# multilib-minimal should _always_ go last in inherit order!!
#
# If you are using in-source builds, then you must run multilib_copy_sources
# at the end of src_prepare!!
#
# If you need generic install rules, use multilib_src_install_all function.


# EAPI=5 is required for meaningful MULTILIB_USEDEP.
