Actually, don't do that. Instead, download autoconf 2.64, build and
install it in a local directory, and use that to rebuild the configure
script. Similarly, you must use automake 1.11.1.
These specific version dependencies are the reason why the files are not
rebuilt by default.

Take a look at libgomp.map. You may need to add your new symbol there.
If this is not for your own private use, add the new symbol under a new
version string.
