Upgrade to 0.6.8

Changes in the makefile:
- package is thread safe (according to Fedora)
- use native build and install

cgdb-0.6.8 (11/13/2014)

  * Fix issue #40, the map commands were adding additional new lines
    to the mappings. For instance, 'imap a b' in the ~/.cgdb/cgdbrc
    file would cause a to map to 'b<cr>' instead of just 'b'.

  * Added feature from issue #29, added 'until' command to CGDB.
  
  * Updated autotools configuration files to satisfy warnings and
    recommendations produced by autotools when run.

  * Fix issue #49, a gcc compiler warning.

  * Fixed a hang consuming 100% CPU usage on OS X Mavericks (github #48).

  * Fixed a hang when quitting cgdb while inferior is running
    (github #1 and #5 and #46). This was believed to be fixed in the last
    release but I've finally reproduced the issue and fixed it for good.

cgdb-0.6.7 (01/14/2013)

  * Changed documentation license from GFDL to GPL (github #6).

  * Fixed a hang on MacOS when quitting cgdb while inferior is running
    (github #1 and #5).

  * Fixed a crash when pressing 'n' in source window (github #5).

  * Fixed a bug opening files (and toggling breakpoints in files) with
    special characters (e.g. space) in their names.

cgdb-0.6.6 (09/06/2011)

  * Fixed a compile error on Cygwin 1.7 (signature for path conversion
    functions changed).

  * Fixed a segfault on 64-bit systems in rline.c due to a missing
    prototype of cgdb_malloc. Thanks to Pietro Cerutti for reporting
    and diagnosing this one!

  * Fixed a bug in the file dialog. When searching for a file,
    and you hit enter to select it, CGDB would sometimes skip to
    the next file that matches and open that file instead.

  * CGDB should now build out of the box on Cygwin again.
    CGDB used to only support building against curses.h. Now
    it also supports building against ncurses/curses.h.

  * No longer set the prompt to (gdb) on startup.
