dnl @synopsis LLNL_CONFIRM_BABEL_PYTHON_SUPPORT
dnl
dnl This is a meta-command that orchestrates a bunch of sub-checks.
dnl I made it a separate M4 Macro to make synchronization between
dnl the main configure script and the runtime configure script easier.
dnl
dnl If Babel support for PYTHON is enabled:
dnl the cpp macro PYTHON_DISABLED is undefined
dnl the automake conditional SUPPORT_PYTHON is true
dnl
dnl If Babel support for PYTHON is disabled:
dnl the cpp macro PYTHON_DISABLED is defined as true
dnl the automake conditional SUPPORT_PYTHON is false
