CC-2193, x64 toolchain

x64 python

# CC-2193, x64 toolchain
# TODO
1. shall we still need to support x86_es
2. Why there is still .pyc in python-lib

# Prepare necessary libraries
* There is no third-party libraries in x64 toolchain (libssl, libcrypto ...)
	1. Build x64 library first
	```
	> @NasX86/Model/TS-X51
	make QOS4=yes BUILD_OPT=pure BASE KERNEL COMLIB NAS_PRELIBRARY SYS_LIBRARY NAS_LIBRARY INSTALL_NAS_LIBRARY 2>&1 | tee build.log
	```
	
	2. Pickup libraries which get lost
		* Actually, build results should be put in **NasX86/LinkFS** not **NasX86/Model/XXX/build/Rootfs**, but some module not follow build rule well we need to pickup those libraries manually.
	```
	> @NasX86/Model/TS-X51
	cp -a build/RootFS/lib/libqsync.so* ../../LinkFS/lib
	cp -a build/RootFS/lib/libgeneral.so* ../../LinkFS/lib
	```
	
	3. make a tarball
	```
	> @NasX86/LinkFS
	tar -jcvf x86_64_ref.tar.bz2 lib include
	```
	
	4. Put tarball to buildserver
	```
	scp x86_64_ref.tar.bz2 anry@192.168.68.231:/home/anry/working
	```
	5. Decorate buildserver
	```
	ssh anry@192.168.68.231
	mkdir -p /home/anry/working/x86_64_ref
	tar -xvf /home/anry/working/x86_64_ref.tar.bz2 -C /home/anry/working/reference/x86_64/

### error: '__PTHREAD_SPINS' undeclared here (not in a function)
link wrong pthreadtypes.h
There is a pthreadtypes.h in /usr/local/x86_64-linux-gnu/ and python's setup.py will add this path to CPPFLAGS automatically.

CC-2193, x64 toolchain

TODO

1. poring python-runtime patch to 2.7.10
2. ask anry should we still need to maintain x86_es

Prepare necessary libraries

• Parameter OPENSSL_VER had been written in makefile

• There is no third-party libraries in x64 toolchain (libssl, libcrypto ...)

  1. Build x64 library first

   > @NasX86/Model/TS-X51
   make QOS4=yes BUILD_OPT=pure BASE KERNEL COMLIB NAS_PRELIBRARY SYS_LIBRARY NAS_LIBRARY INSTALL_NAS_LIBRARY 2>&1 | tee build.log
  

  2. Pickup libraries which get lost
     • Actually, build results should be put in NasX86/LinkFS not NasX86/Model/XXX/build/Rootfs, but some module not follow build rule well we need to pickup those libraries manually.

   > @NasX86/Model/TS-X51
   cp -a build/RootFS/lib/libqsync.so* ../../LinkFS/lib
   cp -a build/RootFS/lib/libgeneral.so* ../../LinkFS/lib
  

  3. make a tarball

   > @NasX86/LinkFS
   tar -jcvf x86_64_ref.tar.bz2 lib include
  

  4. Put tarball to buildserver

   scp x86_64_ref.tar.bz2 anry@192.168.68.231:/home/anry/working
  

  5. Decorate buildserver

   ssh anry@192.168.68.231
   mkdir -p /home/anry/working/x86_64_ref
   tar -xvf /home/anry/working/x86_64_ref.tar.bz2 -C /home/anry/working/x86_64_ref/
