[Bug java/43839] New: libjava incorrectly uses -liconv in testsuite, jni.exp when using --with-libiconv-prefix

["mrs at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

libjava doesn't link libgcj with -liconv during build when
--with-libiconv-prefix=/opt/local is used, and no corresponding -L for the
-liconv is issued on the link line when running the libjava testsuite (jni.exp)
for the FAIL: PR16923 run testcase:

-shared-libgcc -lgcj -liconv  -lm   -o PR16923    (timeout = 300)

The correct bit can be found in the Makefile:

$ grep LTLIBICO x86_64-apple-darwin10/libjava/Makefile 
LTLIBICONV = -L/opt/local/lib -liconv -R/opt/local/lib

The spec file appears it would work:
$ cat x86_64-apple-darwin10/libjava/libgcj.spec
[ ... ]
%rename lib liborig
*lib:  %{s-bc-abi:} -lgcj  -lm -L/opt/local/lib -liconv  -lpthread 
-allow_stack_execute \
 -ldl %(libgcc)  %(liborig)
[ ... ]

as well.

This was reported by Jack, in http://gcc.gnu.org/ml/java/2010-02/msg00003.html,
but seems unresolved.
