It looks like it is geing exported correctly.

It may be an issue with how the objc tests (compile tests, not library tests)
are being called during testing.  Here is an example failure from
gcc/testsuite/objc.dg:

set_ld_library_path_env_vars: ld_library_path=.::/proj/opensrc/nightly/build-ia64-debian-linux-gnu-trunk/obj_gcc/gcc:/proj/opensrc/nightly/build-ia64-debian-linux-gnu-trunk/obj_gcc/gcc:/proj/opensrc/nightly/build-ia64-debian-linux-gnu-trunk/obj_gcc/gcc:/proj/opensrc/nightly/build-ia64-debian-linux-gnu-trunk/obj_gcc/gcc
