[PATCH] Align linkerscript symbols according to ABI

[Alan Modra]

Align dot before symbols defined outside of output sections.  Before _end
is already aligned.

I'm inclined to think that with this patch the alignment in def_symbol
ought to disappear, but for now I'm leaving it in.

	* scripttempl/elf.sc (def_symbol): Tidy excess space.
	(_edata): Align before emitting symbol when SYMBOL_ABI_ALIGNMENT.
