New x86-64/amd64 packages for VGL 2.5.1 and later were uploaded last
night.  Apparently the Docker image I had been using since 2016 to build
official VirtualGL binaries didn't have the x86-64 version of
libstdc++.a installed, so those binaries all depended on libstdc++.so.6
and were thus not cross-compatible (i.e. they probably only worked with
certain Linux flavors.)  Other than changing the libstdc++ dependency to
static rather than dynamic, there should be no other differences in
these new packages.

Whenever I upload new binaries to correct problems such as this, I will
always update the README in the SourceForge files directory (e.g.
https://sourceforge.net/projects/virtualgl/files/2.6/) with information
about which packages were replaced, the date of replacement, and the
reason for it.  All of our Linux packages are signed with GPG, also
(https://virtualgl.org/Downloads/DigitalSignatures).
