[PATCH] configure: add ABIGAIL_DEBUG options

[Matthias Maennich]

When exporting ABIGAIL_DEBUG=1, the binaries compiled are especially
suitable for debugging. The CFLAGS and CXXFLAGS that are added disable
optimization and increase debug information levels.

	* configure.ac: add ABIGAIL_DEBUG environment variable for
	improved debugging capabilities
