Fix bug when optimizing string pools of aligned strings.
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.

* stringpool.cc (Stringpool_template): Don't optimize if section
alignment is greater than sizeof(char).
