Build pycrypto in AIX

1. Download pycrypto-2.6.1 from https://www.dlitz.net/software/pycrypto/

2. Unzip pycrypto
   tar xzvf pycrypto-2.6.1.tar.gz

3. set environment vairable and build source code
   export ac_cv_func_malloc_0_nonnull=yes (It would throw Error “undefined symbol rpl_malloc”)
   python setup.py build
   Refer to iperf-for-arm-cross-compile and openwrt

4. Download dependencies and install them
   http://www.bullfreeware.com/recherche.php

   • gmp-devel-5.1.3-1.aix6.1.ppc.rpm

   http://www.perzl.org/aix/index.php

   • libtomcrypt-1.17-1.aix5.1.ppc.rpm
   • libtomcrypt-devel-1.17-1.aix5.1.ppc.rpm
   • libtommath-0.42.0-1.aix5.1.ppc.rpm
