build: Enable `thread_local` for MinGW-w64 builds
The assumption in the commit 188ca75e5fe4837d16241446558c7566912f67b2
about the broken `thread_local` implementation in GCC was misguided
because the initial failure was not due to GCC, but a bug in the Wine
runtime, as evidenced, for example, here:
- https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=917307
- https://bugs.freedesktop.org/show_bug.cgi?id=108662
Consequently, it is safe to re-enable `thread_local` support for
MinGW-w64 builds.
