Add support for gcc configuration switch --with-cpu. Uses newly added
BR2_GCC_TARGET_CPU from the target config.

This is a very advanced option, and it seems, according to
http://choices.cs.uiuc.edu/exceptions.pdf that SJLJ exceptions aren't
really interesting.
Users really interested by this can always use the
BR2_EXTRA_GCC_CONFIG_OPTIONS is they want.

This option is already part of the gcc configure options through the
BR2_CONFIGURE_BUILD_TOOLS variable (in toolchain/Makefile.in).
Additionnally, the value that was passed in the AVR32 specific case
was incorrect: it was $(STAGING_DIR)/$(REAL_GNU_TARGET_NAME)/bin
instead of $(STAGING_DIR)/usr/$(REAL_GNU_TARGET_NAME)/bin.

This variable is used only once, so let's just hardcode its value at
its call site.

This option is barely used, no-one is maintaining it or extending
it. So let's remove it.

Make the selection of a snapshot version a normal gcc version choice,
and make sure BR2_GCC_VERSION is properly defined.

Hi Eric,
I writing privately since I have not heard from Mike for 2 weeks about
a one line patch to the gcc Makefile.in to allow the extra gcc options
to be passed in. The patch is below and without it -- gcc extra's like
--with-cpu=xscale
do not work.
The patch is as follows:
TARGET_LANGUAGES wasn't being set correctly if you enable GCJ or C++ in
the buildroot config. It looks like INSTALL_LIBSTDCPP and INSTALL_LIBGCJ
were renamed to BR2_INSTALL_... in the config system, but not in the gcc
and ccache makefiles.
