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.
