[PATCH] i386: Also add GLIBC_ABI_GNU2_TLS version [BZ #33129]

[H.J. Lu]

Since the GNU2 TLS run-time bug:

https://sourceware.org/bugzilla/show_bug.cgi?id=31372

affects both i386 and x86-64, also add GLIBC_ABI_GNU2_TLS version to i386
to indicate the working GNU2 TLS run-time.  For x86-64, the additional
GNU2 TLS run-time bug fix is needed for

https://sourceware.org/bugzilla/show_bug.cgi?id=31501
