Eliminate duplicate libiberty when linking gnatbind

[Matt Kraai <kraai at alumni dot cmu dot edu>]

Howdy,

When linking gnatbind, libiberty is include twice on the link
line:

 gcc   -g  -DIN_GCC   -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes  -fno-common   -DHAVE_CONFIG_H  -o gnatbind ada/b_gnatb.o ada/link.o ada/ada.o ada/adaint.o ada/cstreams.o ada/cio.o ada/ali.o ada/ali-util.o ada/alloc.o ada/a-tags.o ada/a-stream.o ada/bcheck.o ada/binde.o ada/binderr.o ada/bindgen.o ada/bindusg.o ada/butil.o ada/casing.o ada/csets.o ada/debug.o ada/fname.o ada/gnat.o ada/g-hesora.o ada/g-htable.o ada/g-os_lib.o ada/s-crc32.o ada/fmap.o ada/gnatbind.o ada/gnatvsn.o ada/hostparm.o ada/krunch.o ada/namet.o ada/opt.o ada/osint.o ada/osint-b.o ada/output.o ada/rident.o ada/s-assert.o ada/s-parame.o ada/s-sopco3.o ada/s-sopco4.o ada/s-sopco5.o ada/s-stache.o ada/s-stalib.o ada/s-stoele.o ada/s-imgenu.o ada/s-strops.o ada/s-soflin.o ada/s-wchcon.o ada/s-wchjis.o ada/sdefault.o ada/switch.o ada/switch-b.o ada/stylesw.o ada/validsw.o ada/system.o ada/table.o ada/tree_io.o ada/types.o ada/widechar.o ada/raise.o ada/exit.o ada/argv.o ada/init.o ada/adafinal.o ada/s-wchcnv.o ada/s-exctab.o ada/a-except.o ada/s-memory.o ada/s-traceb.o ada/tracebak.o ada/s-mastop.o ada/s-except.o ada/s-secsta.o ada/atree.o ada/scans.o ada/einfo.o ada/sinfo.o ada/scn.o ada/sinput.o ada/sinput-l.o ada/targparm.o ada/errout.o ada/style.o ada/stand.o ada/lib.o ada/uintp.o ada/elists.o ada/nlists.o ada/stringt.o ada/snames.o ada/uname.o ada/urealp.o prefix.o version.o \
      ../libiberty/libiberty.a   ../libiberty/libiberty.a 

Since it is already included in $(LIBS), there is no need to
explicitly link against it.

The following patch removes the duplicate.  It was bootstrapped
and regression tested on powerpc-unknown-linux-gnu.

OK to commit?
