replacing libglvnd with mesa libraries as much as possible!

[Demo]

Hello folks ...

As the title suggests, I'm trying to put all possibly optimized mesa libraries for my machine as much as possible instead of libglvnd libraries, almost everything is going well, however in order to support glx libglvnd always produces it's own version of libgl.so which is different than the mesa's library of course and not linked against the same libraries, consequently mesa's libgl.so doesn't call libglx.so, and mesa doesn't seem to have the facility to produce a parallel libglx.so ...

I want either to avoid the collision by not getting libglvnd to produce libgl.so, or getting mesa to produce libglx.so!

I know it may sound stupid to some, but I searched and tried for a few hours with no joy so I thought I could ask, and please don't ask me why I'm doing it, I have a slow machine and I'm an optimization geek ...

Any suggestions?!

Annoyingly libglvnd was previously an optional USE dependency on Gentoo. It's unnecessary on single GPU or single vendor multi-GPU systems and does slightly impact performance. Makes life easier for non-source based distributions...

Anyway, create a dummy libglvnd-9999.ebuild package and (as I couldn't figure out how to make it install as multilib) edit the /var/db/pkg/media-libs/libglvnd-9999/USE (and maybe IUSE and IUSE_EFFECTIVE) files post-install and add the strings abi_x86_32 and abi_x86_64.
