install.texi says "As of GCC 3.3, binutils 2.13.1 or later is required for 
this platform." for i?86-*-linux*, with no specific version requirement 
mentioned for x86_64.  gcc/configure.ac believes that 2.14 has TLS support 
for both platforms.

(Maybe each GCC release should declare a minimum supported binutils 
version across all platforms - say the last FSF release as of when Stage 3 
is entered - and require that if you are using GNU binutils then you must 
use at least that version, rather than claiming probably untested support 
for random older versions.)
