Support for LOCAL_HAL_STATIC_LIBRARIES

Now you can have a board config variable BOARD_HAL_STATIC_LIBRARIES,
which is a list of board-specific HAL static library names with pattern
"lib<library_name>.<board_specific_suffix>". LOCAL_HAL_STATIC_LIBRARIES
is a list of "lib<library_name>" and any matched
BOARD_HAL_STATIC_LIBRARIES will be added to the LOCAL_STATIC_LIBRARIES;
if no match is found, lib<library_name>.default will be used.
