Added target.

The logs are available at:

http://builds.linaro.org/toolchain/gcc-4.7~svn179959/logs/armv7l-natty-cbuild199-tcpanda06-cortexa9r1/

GCC was configured with:

--prefix=/scratch/cbuild/slave/slaves/tcpanda06/gcc-4.7~svn179959/gcc/default/install
--enable-languages=c,c++,objc,obj-c++,fortran,lto --with-mode=thumb
--with-arch=armv7-a --with-tune=cortex-a9 --with-float=softfp --with-fpu=neon

More information on the host is at:

http://builds.linaro.org/toolchain/gcc-4.7~svn179959/logs/armv7l-natty-cbuild199-tcpanda06-cortexa9r1/host.txt

The test case is gcc/testsuite/gcc.c-torture/compile/limits-fndefn.c.

I'm building r180460 at the moment and will see how that goes.
