Hi

We need to add the symbols for to_chars and from_chars for the
long double cases.

The testsuite test cases fail to build without this, so there’s no need
for an additional test.

Tested on powerpc-darwin9.
OK for master?
thanks
Iain

        * config/os/bsd/darwin/ppc-extra.ver: Add matching for
        to_chars and from_chars for long double.
