The command line is

/export/gnu/import/git/gcc-test-intel64/bld/gcc/xgcc
-B/export/gnu/import/git/gcc-test-intel64/bld/gcc/
/export/gnu/import/git/gcc-test-intel64/src-trunk/libjava/testsuite/libjava.jni/invocation/PR16923.c
-I. -I..
-I/export/gnu/import/git/gcc-test-intel64/src-trunk/libjava/testsuite/libjava.jni
-I/export/gnu/import/git/gcc-test-intel64/src-trunk/libjava/testsuite/../include
-I/export/gnu/import/git/gcc-test-intel64/src-trunk/libjava/testsuite/../classpath/include
-fdollars-in-identifiers
-L/export/gnu/import/git/gcc-test-intel64/bld/x86_64-unknown-linux-gnu/32/libjava/.libs
-ljvm -lm -m32 -o PR16923

ld finds libgcj.so via -ljvm.  It should reject it:

/usr/local/bin/ld: /export/gnu/import/git/gcc-test-intel64/bld/gcc/crtbegin.o:
undefined reference to symbol '_Jv_RegisterClasses'
/usr/local/bin/ld: note: '_Jv_RegisterClasses' is defined in DSO
/export/gnu/import/git/gcc-test-intel64/bld/x86_64-unknown-linux-gnu/libjava/.libs/libgcj.so.14
so try adding it to the linker command line
/export/gnu/import/git/gcc-test-intel64/bld/x86_64-unknown-linux-gnu/libjava/.libs/libgcj.so.14:
could not read symbols: Invalid operation
