We'll instead use a git submodule to pull from our unbound repo.

-# SYNOPSIS
-#
-#   AC_PROG_SWIG([major.minor.micro])
-#
-# DESCRIPTION
-#
-#   This macro searches for a SWIG installation on your system. If found you
-#   should call SWIG via $(SWIG). You can use the optional first argument to
-#   check if the version of the available SWIG is greater than or equal to
-#   the value of the argument. It should have the format: N[.N[.N]] (N is a
-#   number between 0 and 999. Only the first N is mandatory.)
-#
-#   If the version argument is given (e.g. 1.3.17), AC_PROG_SWIG checks that
-#   the swig package is this version number or higher.
-#
-#   In configure.in, use as:
-#
-#     AC_PROG_SWIG(1.3.17)
-#     SWIG_ENABLE_CXX
-#     SWIG_MULTI_MODULE_SUPPORT
-#     SWIG_PYTHON
