description:
make stack size limit (both initial and maximum) for native code
the double of that in 32-but emul mode, so that code which works
in emulation (or on the i386 port) will likely not overflow the
stack if built as native 64-bit program
This is still very conservative.
(before, the max stack size was natively even less than for 32bit emul)
