That's pretty old.  Can you reproduce the problem with diffutils 3.3?  I can't, 
so possibly the bug is fixed already, which would be nice.

That's quite a few flags.  What happens if you omit them?

Here's how I attempted to reproduce the problem with diffutils 3.3 on my AIX 
environment.  I built with './configure CC=xlc_r'.  My version info is:

$ uname -a
AIX power-aix 1 7 00F84C0C4C00
$ oslevel -s
7100-02-02-1316
$ xlc_r -qversion

Moved to 3.3, same failure

same loader

$ `which ld` -V
/usr/bin/ld: LD 7.1.3(4/1/14)

  (cmp, diff, diff3 are ok)

  CC       sdiff.o
  CCLD     sdiff
ld: 0711-317 ERROR: Undefined symbol: @4 <at> null_action
ld: 0711-345 Use the -bloadmap or -bnoquiet option to obtain more

Sadly either -bnoquiet and -bnoquiet cause ./configure to crash, so in src
I appended to the Makefile LDFLAGS -bnoquiet


Removing all the options and then sequentially adding them back the
offender was the setting of the optimizer to level 5 (-O5).

Setting it to level 4 (-O4) gave no errors

Just a side note even with no options make check fails at

     CC       test-fcntl-h.o
      "test-fcntl-h.c", line 76.10: 1506-052 (S) Duplicate case label for
value 0. Labels must be unique.
      "test-fcntl-h.c", line 118.10: 1506-052 (S) Duplicate case label for
value 0. Labels must be unique.

       Other GNU packages also fail make check here as well

The error shows up with the optimizer is set to level 5 -O5. The difference
between this level and level 4 -O4 is
with level 5 the option qipa is change from the default of object
(-qipa=object) to level=2 (-qipa=level=2).

-O5 is the same as  ... -O4 -qipa=level=2 ...

As another side note, I've build about 6-7 other GNU packages with -O5 and
no issues, or at least no issues with O5.

Update ...

hacking in -bnoquiet to the src/Makefile for LDFLAGS

Please close.

The issue was resolved by building and installing GNU libiconv

This helped
