[COMMITTED] gcc: xtensa: make TARGET_HAVE_TLS definition static

[Max Filippov via Gcc-patches]

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

Tested with xtensa-linux-uclibc, no new regression failures.
Committed to master.

        * 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.
