Further mingw-w64/gcc build tweaks

Commit 6481bb22b (win32: use 64-bit time on 32-bit platforms) fails
to build with mingw32-gcc prior to mingw-w64 10.0.0.

Don't used 64-bit time for such builds.

mingw-w64 7.0.0 and below don't have some definitions required for
native TLS support.  This is enabled by default in the 64-bit
Unicode build.

Add the definitions required for the default build.  TLS 1.3
support needs more but isn't enabled by default.
