[PULL 26/27] configure: Remove the check for the __thread keyword

Posted by Paolo Bonzini 4 years, 3 months ago

From: Thomas Huth <thuth@redhat.com>

We recently bumped our minimum required version of GCC to 7.4
and Clang to 6.0, and those compiler versions should support
the __thread keyword already.
