Created attachment 368828 [details, diff] libtool-2.4.2.ebuild.patch multilib patch for libtool - please review. The ebuild still had EAPI=2 because of bug 356089. I think as of today, having ebuilds at EAPI=4 shouldn't make any problems anymore. I also had to replace the dosed command with the sed itself.
Patch looks good to me, but EAPI bump needs to be approved by base-system herd.
Following late approvals for EAPI=4, I went ahead and committed it p.masked. We can still discuss and change it before it's unmasked, and in the meantime users can test it a bit. +*libtool-2.4.2-r1 (02 May 2014) + + 02 May 2014; Michał Górny <mgorny@gentoo.org> +libtool-2.4.2-r1.ebuild, + libtool-9999.ebuild: + Introduce multilib support, bug #499390.
I had some trouble with 2.4.2-r1 (perhaps limited to prefix?). Details, including a patch (though there might be a better way, too) are here: https://bugs.gentoo.org/show_bug.cgi?id=516598
