x86-64 -mtls-dialect=gnu2 change landed in rawhide
This was originally approved as part of the Fedora 40 toolchain update,
but we encountered a GCC/glibc ABI mismatch which we fixed in glibc.
I couldn't do a full distribution rebuild test (and there was just one
package that showed the ABI bug in the first run!), but I tested
building bash, lua, libomp in a side tag before merging the
redhat-rpm-config update.
Thanks,
Florian
