    gcc: xtensa: make TARGET_HAVE_TLS definition static
    
    Remove TARGET_THREADPTR reference from TARGET_HAVE_TLS to avoid
    static data initialization dependency on xtensa core configuration.

            * config/xtensa/xtensa.c (TARGET_HAVE_TLS): Remove
            TARGET_THREADPTR reference.
            (xtensa_tls_symbol_p, xtensa_tls_referenced_p): Use
            targetm.have_tls instead of TARGET_HAVE_TLS.
            (xtensa_option_override): Set targetm.have_tls to false in
            configurations without THREADPTR.
