* New configure options
--with-intel-pt
This configure option allows the user to build GDB with support for
Intel(R) Processor Trace (default: auto). This requires libipt.
--with-libipt-prefix=PATH
Specify the path to the version of libipt that GDB should use.
$PATH/include should contain the intel-pt.h header and
$PATH/lib should contain the libipt.so library.
*** Changes in GDB 7.9.1
* Python Scripting
