A .la file is a text file containing metadata for a library; they are
created by and used by libtool.

In particular, libtool cannot use a static library without the
corresponding .la file, as static libraries don't include dependency
information.

I suggest doing:

	ln -s libstdc++.so.6 /usr/lib/libstdc++.so

then start building GDAL from the beginning (i.e. make distclean,
configure, ...).

Hopefully, that will cause it to pick up the shared C++ library rather
than the static version.
