Jan,
I notice the x86 default -mtls-dialect is GNU not GNU2.  The latter was 
added in 2006.  Is there a reason not to default to it now?  (perhaps 
because of the ldso dependency?)

You may have noticed.  There is zero test for -mtls-dialect=gnu2 on x86
in GCC and I only added one -mtls-dialect-gnu2 in glibc last year when
I fixed GNU2 TLS bug in glibc:

https://sourceware.org/bugzilla/show_bug.cgi?id=20309

So effectively, there is very little test for -mtls-dialect-gnu2 on x86.
