[PATCH] Avoid non-C++-enabled babeltrace versions

- Subject: [PATCH] Avoid non-C++-enabled babeltrace versions
- Authentication-results: sourceware.org; auth=none
In some babeltrace versions before 1.2.0, the header file iterator.h is
not fully enabled for use from C++, since it contains an anonymous enum
in a struct declaration. This is fixed in later babeltrace versions:
https://lists.lttng.org/pipermail/lttng-dev/2013-September/021411.html
Now that GDB is compiled with C++, the GDB build fails on a system with
such a babeltrace version: the compiler complains about a missing
declaration of BT_SEEK_BEGIN in ctf.c.
This patch enhances the configure check to recognize such babeltrace
versions as unusable for GDB.
gdb/ChangeLog:
* configure.ac: Enhance configure check for babeltrace to reject
non-C++-enabled versions.
* configure: Regenerate.
