This also report bug fixes about data alignment and bss storage to EFM32 &
LM3S targets.
Note: removed chrysn copyright statement as the file is a verbatim copy of
previous files.
That way, data source address does not depend on any other unrelated change in
linker script.
This also fixes cases when .data input section is aligned on 8 bytes. The new
version does not provide any address for the output section so that it is
aligned to the strictest input section. The _data_loadaddr symbol will
always take this alignment into account.
