Merge branch 'danpeirce-master'
stmhal: For non-debug compile, enable CC/LD opt to remove dead code.

Saves over 35k ROM due to elimination of unused HAL functions.  All
tests pass.

Addresses issue #702.
tests: Wait for just over 1 sec when testing RTC.

Waiting for 1000ms between seconds of RTC is sometimes too quick.
Waiting for 1001ms is enough for the RTC to pass 1 second.
Merge branch 'master' into iabdalkader-cc3k-update
