Avoid non-C++-enabled babeltrace versions
In some babeltrace versions before 1.2.0, the header file iterator.h declares the enum values `BT_SEEK_*' within the struct declaration of bt_iter_pos. The enum values are supposed to be globally-scoped, which works for C, but not for C++. Later babeltrace versions declare the enum outside the struct: 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 an affected 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.
