Currently, sections within .text/.rodata/.data/.bss are emitted in the
order they are seen by the linker. This leads to wasted space, when a
section with a larger alignment follows one with a smaller alignment.
We can avoid this wasted space by sorting the sections.
To take full advantage of this, we must disable generation of common
symbols, so "common" data can be sorted along with the rest of .bss.
An example of the improvement, from `make DEBUG=1 PLAT=sun50i_a64 bl31`:
.text => no change
.rodata => 16 bytes saved
.data => 11 bytes saved
.bss => 576 bytes saved
As a side effect, the addition of `-fno-common` in TF_CFLAGS makes it
easier to spot bugs in header files.

The macro SORT_BY_ALIGNMENT is used for .text* and .rodata*. This allows
reducing the space lost to object alignment. This is an alignment with
the following patch:
ebd6efae67c6a086bc97d807a638bde324d936dc
Some comments are also aligned with other linker scripts.
