    Problem Text
    The problem is that the test binary, T.chroot, forks and execs the chroot_t4
    binary. chroot_t4 is not linked archived, so uses a shared-library version
    of libc. This means chroot_t4 needs to have access to the file
    /usr/bin/dld.sl in order to execute. When chroot_t4 is exec'd by T.chroot,
    the exec fails with errno 2 (ENOENT) because /usr/bin/dld.sl couldn't be
    found. The reason it couldn't be found is that T.chroot has already done a
    chroot (change root) such that the /usr/bin directory is not accessible to
    T.chroot and its children.

    The fix for this problem is to link chroot_t4 archived. It is now linked
    archive, except for libc. When the following change was made, the tests
    ran and passed. The change is to Makefile, line 98 in the path:

    /var/opt/stdenv/vsx/vsx4/tset/XOPEN.os/procenv/chroot

    chroot_t4: $(OFILES4) $(LIBS)
    $(CC) -Wl,-a,archive -o $@ $(OFILES4) $(LIBS)
    ^^^^^^^^^^^^^^
    $(SYSLIBS) $(LDFLAGS)
    Test Output
    /tset/XOPEN.os/procenv/chroot/T.chroot 4 Unresolved

    Test Description:
    The root directory is inherited by all processes created via
    a. a fork() system call;
    b. an exec() system call;

    Test Information:
    child process gave unexpected exit code 2

    Status Complete
    Review Recommendation No Resolution Given
    Review Response
    This test is already waivered in VSX 4.3.5 as waiver TSD4.217 and no further
    waiver is needed. It is recommended that this request is refused.

    As to the specific proposed solution, this is not a generic solution which
    could be applied to all XPG4 conforming systems, though it could be supplied
    via a compile time parameter.
