[PATCH obv] Fix non stopping breakpoint on newer compilers.

[Walfred Tedeschi <walfred.tedeschi@intel.com>]

The breakpoint presented in the return statement was not activated while
compiling the test with gcc 4.9.2.  Added a dummy statement to allow the
breakpoint again.

gdb/testsuite:

	* i386-mpx-map.c (foo): Add dummy statement to trigger breakpoint.
