    aarch64: Accept PLT calls to __getauxval within libc.so

    When using outline atomics (-moutline-atomics, the default for ARMv8-A

    starting with GCC 10), libgcc contains an ELF constructor which calls

    __getauxval.  This code is built outside of glibc, so none of its

    internal PLT avoidance schemes can be applied to it.  This change

    suppresses the elf/check-localplt failure.
