Patrick Mahoney 1e06594c0c mariadb: Patch to compile on OS X.
* perl is required at build time on darwin. Copied from the
  mysql/5.5.x.nix

* CMake on darwin creates shared libraries with relative 'install_name'
  paths which are made absolute by fixDarwinDylibNames.

  See http://answers.opencv.org/question/4134/cmake-install_name_tool-absolute-path-for-library/

* The asm patch was needed to compile on darwin, though I do not
  understand what is going on. Error before the patch:
