Set SDK_VENDOR to '-w64', which makes the host triplet match what GCC
expect to find when using mingw32-w64. This enables features that are
not functional in the classic mingw32, but have been implemented in the
mingw32-w64.

Disable 32bit libs from the runtime component when compiling for 64bit,
which were enabled as a side effect of the GCC config change.
