A patch for portage

As explained on gentoo-dev [1], env-update should pass '-X' to ldconfig in order to preserve SONAME symlinks installed by portage. This fixes downgrade issues with preserved-libs.

Opening a bug to track other 'ldconfig' calls.

Maybe we should add a pre-merge symlink check for $D. Then if necessary we can generate missing symlinks and trigger a QA Notice.

Well, I did a massive 'qlist -a' check on my packages and none seem not to provide those symlinks. But such a check is a good idea indeed. Even better than blindly running 'ldconfig -N -n ${D}/usr/lib'.

I've made it automatically create symlinks after src_install, since that's when NEEDED.ELF.2 is generated:

And the env-update patch is applied:

This is confined to global libdirs now:

This is in 2.2.0_alpha42, but I'll leave this bug open until it's in an unmasked release.

This is fixed in 2.1.10.4.
