i386: Add GLIBC_ABI_GNU_TLS version dependency

On Linux/i386, programs and shared libraries compiled with
-mtls-dialect=gnu may fail silently at run-time against glibc without
the GNU TLS run-time fix for:

https://sourceware.org/bugzilla/show_bug.cgi?id=32996

The glibc version tag, GLIBC_ABI_GNU_TLS, has been added to indicate
that glibc has the working GNU TLS run-time:

    i386: Add GLIBC_ABI_GNU_TLS version [BZ #33221]

Add the --gnu-tls-tag option to x86-64 ELF linker to add the
GLIBC_ABI_GNU_TLS version dependency in output programs and shared
libraries when linking against glibc if input relocatable object files
call ___tls_get_addr.  The output will fail to load and run at run-time
against glibc which doesn't define the GLIBC_ABI_GNU_TLS version.

Add the --enable-gnu-tls-tag configure option to enable --gnu-tls-tag
by default.  If unspecified, linker will add the GLIBC_ABI_GNU_TLS
version dependency if input call ___tls_get_addr and libc.so defines
the GLIBC_ABI_GNU2_TLS version.
