<pre>Following tests fail on arm-linux:
TestWatchLocationWithWatchSet.py
TestStepOverWatchpoint.py
Ptrace interface fails to set read/write watchpoints on single byte variables
which are not word aligned.
Following commands fail, in case of TestStepOverWatchpoint:
watchpoint set variable -w read g_watch_me_write
Following commands fail, in case of TestWatchLocationWithWatchSet:
watchpoint set expression -w write -s 1 -- g_char_ptr + 7
Need to do further investigation on how to make sure we can select individual
bytes while setting watchpoints on arm.</pre>
