Largely irrelevant information: symbol versioning is supported by the
GNU linker for any ELF platform.  It is not really a GNU extension--it
was developed by Sun, and the GNU implementation follows the Sun
linker implementation.  But the GNU implementation is not quite
identical, and does have some extensions.
