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.
