Add 64-bit windows cross-compiles
This is mostly the same as the existing 2ND_HOST / HOST_CROSS support.
The interesting thing I did here was make x86 the 'first' architecture,
and x86_64 the second. This way LOCAL_MULTILIB := first defaults to
32-bit windows modules.
windows-x86/bin <- defaults to 32-bit executables
windows-x86/lib <- 32-bit libraries, like before
windows-x86/lib64 <- 64-bit libraries
windows-x86/obj <- 32-bit intermediates
windows-x86/obj64 <- 64-bit intermediates
Then modules are registered with the names:
host_cross_liblog <- 32-bit, like before
host_cross_liblog_64 <- 64-bit
