re PR libgcj/25816 (Configure detects TLS, but glibc does not support it.)
PR java/25816
* configure.ac (enable_tls): New enable option.
(HAVE_AS_TLS): Don't do assembler check if enable_tls set.
* configure: Regenerate.
* doc/install.texi (--enable-tls): Document new option.
(--disable-tls): Ditto.
