The patch which moved libio.h proper into the bits directory also
changed the name of its guard macro, and I neglected to check whether
anything depended on that name.  It turns out that there is a
conditionally-used bits header that looks at it; this broke both the
glibc and the libgcc build on at least sparc64-*-* and sparcv9-*-*.

I have pushed this immediately, ahead of testing, since it should correct
build failures.  Testing is in progress.

	* libio/bits/libio-ldbl.h: Correct check for improper
	inclusion.  Add own multiple include guard.
