configure: Add option to disable abidb

While looking at packaging libabigail for EPEL8, it turned out abidb
requires python 3.9 for the type hints on function definitions.  Yet,
EPEL8 has an older python.

This patch adds a --disable-abidb option to configure to handle EPEL8.

	* configure.ac: Add a --disable-abidb option to configure to
	disable the abidb tool and related tests.
