   4 Subject: [PATCH] Adjust library/header paths for cross-compilation
   5
   6 When cross-compiling third-party extensions, the get_python_inc() or
   7 get_python_lib() can be called, to return the path to headers or
   8 libraries. However, they use the sys.prefix of the host Python, which
   9 returns incorrect paths when cross-compiling (paths pointing to host
  10 headers and libraries).
  11
  12 In order to fix this, we introduce the _python_sysroot, _python_prefix
  13 and _python_exec_prefix variables, that allow to override these
  14 values, and get correct header/library paths when cross-compiling
  15 third-party Python modules.
