[buildrobot][patch] aarch64: Fix ifunc support

[Jan-Benedict Glaw <jbglaw at lug-owl dot de>]

Hi!

My build robot[1] found a breakage[2] after the recently committed
ifunc support for aarch64:

/bin/sh ./libtool --tag=CC   --mode=link gcc -W -Wall -Wstrict-prototypes -Wmissing-prototypes -Wshadow -Werror -g -O2   -o as-new app.o as.o atof-generic.o compress-debug.o cond.o depend.o dwarf2dbg.o dw2gencfi.o ecoff.o ehopt.o expr.o flonum-copy.o flonum-konst.o flonum-mult.o frags.o hash.o input-file.o input-scrub.o listing.o literal.o macro.o messages.o output-file.o read.o remap.o sb.o stabs.o subsegs.o symbols.o write.o tc-aarch64.o obj-elf.o atof-ieee.o  ../opcodes/libopcodes.la ../bfd/libbfd.la ../libiberty/libiberty.a   -lz

Simple fix: commit regenerated bfd/configure. Albeit mentioned in the
Changelog, it's missing from the commit:

	* configure: Regenerate.
