Make Blender builds running with VFX Platform recommandations (glibc)

Hi @VincentGires VFXPlatform adherence has already been discussed and is not going to happen anytime soon at least not until B28 will be out of beta and for some time.
To be said though, blender is not far already from having many dependencies close.

For building on c7 , there’s also a discussion about it already: Unable to run blender 2.80 in RHEL/CentOS 7 - #44 by AhmedBarakat

hope it helps.
