Add (undocumented) support for version suffixes

Browse Source 
Allow appending arbitrary text to the libabigail version string
representation. That is useful to identify custom versions of the
library (e.g. development versions or versions of a particular origin).

The feature can be enabled by passing VERSION_SUFFIX to `configure`,
e.g.

  $ configure VERSION_SUFFIX="-dev"

That will extend the version string to (currently) 1.7.0-dev.
The behaviour before this patch remains the default behaviour of not
appending any additional text.

The feature stays intentionally undocumented as the main release of
libabigail will usually not carry a version suffix.

	* configure.ac: add substitution for VERSION_SUFFIX
	* include/abg-version.h.in: add define for ABIGAIL_VERSION_SUFFIX
	* include/abg-config.h(abigail_get_library_version): add support
	for a version suffix
	* src/abg-config.cc(abigail_get_library_version): Likewise.
	* src/abg-tools-utils.cc(get_library_version_string): Likewise.
