It looks like that DT_RUNPATH isn't properly handled.

--- Comment #1 from H.J. Lu <hjl.tools at gmail dot com> ---
The difference between DT_RPATH and DT_RUNPATH is that

1. Directories specified by DT_RPATH are searched before directories specified
by LD_LIBRARY_PATH.
2. Directories specified by DT_RUNPATH are searched after directories specified
by LD_LIBRARY_PATH.

It looks like a --enable-hardcoded-path-in-tests issue.

--- Comment #4 from H.J. Lu <hjl.tools at gmail dot com> ---
It happens on Fedora 34/35 since linker defaults to --enable-new-dtags.

    Disable DT_RUNPATH on NSS tests [BZ #28455]

    The glibc internal NSS functions should always load NSS modules from
    the system.  For testing purpose, disable DT_RUNPATH on NSS tests so
    that the glibc internal NSS functions can load testing NSS modules
    via DT_RPATH.

    This partially fixes BZ #28455.

    elf: Also try DT_RUNPATH for LD_AUDIT dlopen [BZ #28455]

    DT_RUNPATH is only used to find the immediate dependencies of the
    executable or shared object containing the DT_RUNPATH entry.  Update
    LD_AUDIT dlopen call to try the DT_RUNPATH entry of the executable.

    Add tst-audit14a, which is copied from tst-audit14, to DT_RUNPATH and
    build tst-audit14 with -Wl,--disable-new-dtags to test DT_RPATH.

    This partially fixes BZ #28455.

    Add and use link-test-modules-rpath-link [BZ #28455]

    DT_RUNPATH is only used to find the immediate dependencies of the
    executable or shared object containing the DT_RUNPATH entry:

    1. Define link-test-modules-rpath-link if $(build-hardcoded-path-in-tests)
    is yes.
    2. Use $(link-test-modules-rpath-link) in build-module-helper so that
    test modules can dlopen modules with DT_RUNPATH.
    3. Add a test to show why link-test-modules-rpath-link is needed.

    This partially fixes BZ #28455.
