[gold commit] PR gold/18010: Fix bug when optimizing string pools of aligned strings

[Cary Coutant]

Tail optimization of string pools (enabled when linker is run with -O2
or greater) should not be done when the section alignment is greater
than the size of the characters in the strings; otherwise, unaligned
strings may result.

I've committed this patch to disable tail optimization when the
alignment is larger than the character size.

        alignment is greater than sizeof(char).
