I'm dropping this patch after realizing that it's not necessary after
all, at least for use with the libdfp that's being developed within
the EGLIBC project.  Applications that need full support for decimal
float will link against libdfp and get different versions of the
runtime support that are provided there, without needing to actually
override versions in a shared library provided by GCC.
