[PATCH][GOLD] Fix sorting of .init_array and .fini_array input sections.

[=?big5?b?RG91ZyBLd2FuICjD9q62vHcp?= <dougkwan at google dot com>]

Hi,

This patch fixes sorting of init_array and .fini_array input sections
so that the behaviour is similar to that of ld, which has been fixed
by Alan's recent patch:

This was tested on both x86_64 and ARM Linux.  All tests passed on
both platforms.
