This is a question for the gcc mailing list (gcc@gcc.gnu.org) not the 
binutils mailing list.

The answer is that for a sufficiently new version of gcc you can just 
run it with the "-v" command line option.  E.g. on my work machine:

   % gcc -v
   Reading specs from /usr/lib/gcc/x86_64-redhat-linux/3.4.6/specs
   Configured with: ../configure --prefix=/usr --mandir=/usr/share/man
   --infodir=/usr/share/info --enable-shared --enable-threads=posix
   --disable-checking --with-system-zlib --enable-__cxa_atexit
   --disable-libunwind-exceptions --enable-java-awt=gtk
   --host=x86_64-redhat-linux
   Thread model: posix
   gcc version 3.4.6 20060404 (Red Hat 3.4.6-3)

The thread model is the second to last line in the output.

Cheers
