Support appears to have been added by

2002-03-04  H.J. Lu <hjl at gnu.org>

        * scripttempl/elf.sc: Put .preinit_array, .init_array and
        .fini_array in the data segment.

2002-03-04  Alan Modra  <amodra at bigpond.net.au>

        * scripttempl/elf.sc: Correct syntax errors in 2002-03-01 commit.

2002-03-01  David Mosberger  <davidm at hpl.hp.com>

        * scripttempl/elf.sc (SECTIONS): Add entries for .preinit_array,
        .init_array, and .fini_array.

so any version from nearly the past four years should be OK.  In any case, 
binutils build doesn't look for library features so there is no need to 
rebuild binutils if you have a suitable version, i.e. 2.12.1 or later (the 
changes were after 2.12 branched but merged into 2.12.1).
