mingw-w64 cross compile

	# We use Ubuntu 14.04 to build a native gcc for win32 with multilib support
	#
	# Based on:
	# http://sourceforge.net/p/mingw-w64/wiki2/Native%20Win64%20compiler/
	# http://sourceforge.net/p/mingw-w64/code/HEAD/tree/stable/v3.x/mingw-w64-doc/howto-build/mingw-w64-howto-build.txt?format=raw
	#
	# Cross compiling notes:
	# - The minor version of gcc must match that of our cross compiler (4.8 in this case)
	# - Important parameters: http://gcc.gnu.org/onlinedocs/gccint/Configure-Terms.html

virtio-rngのちょっとしたメモ

	# RNG@乱数ジェネレーターのメモ

	Host:
	- Hostではhavegedやrng-toolsを使って乱数を生成して、virtio-rng経由でGuestに渡す
	- rngd(TPM,DRNG) or haveged(Software) -> /dev/random -> (qemu-kvm) -> Guestへ

	Guest:
	- Guestではrng-toolsを使って/dev/hwrngから乱数を生成して/dev/randomに書き込む
	- rng-tools(/dev/hwrng) -> /dev/random
