[Read-only notification of GnuTLS library development activities]

I don't think those are related. This is the `/proc/cpuinfo` from my VM:

As you can see the `xsave` and `avx` are absent (also `avx2` which was set in the bug you quoted).

Unfortunately I have a hard time to get gnutls compiled on that machine.
