Here's the patch that removes it.  I think this should go in before
4.7.0 is released: if the function is added later, it would incorrectly
end up in the LIBITM_1.0, defeating the purpose of symbol versioning.

Bootstrapped without regressions on i386-pc-solaris2.11 and verified
that the symbol version info is unchanged.

Ok for mainline?
