Bootstrapping sparc-sun-solaris2.5.1 - missing rules for some .o files in libio

[Jim Wilson]

	When it comes time to build libio under libraries/libio, the "ar" step
	fails because several objects never got made.  Rules for these objects
	were missing from the Makefile.

Looking in our mail archives, I see two other reports of this same problem,
but no indication of the solution.

One message said that this problem could be worked around by adding the
5 missing *.c files (peekc.c, iogetc.c, ioputc.c, iofeof.c, and ioferror.c)
to DEPEND_SOURCES in libio/config.shared.  You could try doing that.

If you could perhaps figure out why this problem is happening for you
that would be useful.  We could then document why it is failing.
