>Description:
gcc's configure script attempts to determine the "ld" version string in one of it's tests but fails to do so when used with the latest FSF release of binutils (2.13.2.1).
The configury works fine when used with version 2.13.2 so it appears the extra digit on the current release is confusing the regexp. The regexp needs to be reworked but I haven't been able to come up with a working version up to this point.
This is a critical problem as it results in gcc not correctly identifying that our binutils has .hidden support which then results in non-functioning __cxa_atexit support in glibc which is obviously bad when gcc is now always configured with --enable__cxa_atexit. Ultimate result is segfaulting c++ binaries.

>How-To-Repeat:
Install FSF binutils-2.13.2.1 then configure gcc to use those binutils and watch as it says:-
checking assembler hidden support... no
>Fix:
Fix the regexp in the configure script.
