I notice a problem when I try to build gst-plugins-good.  Because AS_LIBTOOL_TAGS has ([CXX]) as an argument, it tries to use the C++ compiler for doing the 
following "nm" check in configure.

checking command to parse /usr/ccs/bin/nm -p output from $compiler object

But the problem is that if this command ends up compiling a test program and the compile program it ends up generating uses the C++ compiler but the CFLAGS I have set up, which isn't valid for the C++ compiler.

This causes configure to think it fails, and the generated libtool doesn't set global_symbol_pipe right, and the module build breaks when it tries to link.

I'm attaching a simple patch that removes the "([CXX])" from this macro, which makes things work better.  I notice that this is how the gst-plugins-base works.  I don't know why we are specifying using the C++ compiler here since gst-plugins-good doesn't even have any C++ code in it.

Can this patch go into the build?  Otherwise we'll need to patch the code locally with this change to get gst-plugins-good to build with out build system.
