[Patch, Newlib/Libm] Avoid index.html and Index.html file name clash on platform like windows

[Jeff Johnston]

I think it is fine in libc and libm should probably do the same.  The Index chapter in libc should not be a numbered chapter.  The node refers to it properly.

From the texinfo documentation on @unnumbered/@appendix:

"Use the @unnumbered command to start a chapter-level element that appears without chapter numbers of any kind. Use the @appendix command to start an appendix that is labeled by letter (‘A’, ‘B’, …) instead of by number; appendices are also at the chapter level of structuring."

"Write an @appendix or @unnumbered command at the beginning of a line and follow it on the same line by the title, just as with @chapter.

I think so, but I'm not a texinfo expert.  I noticed that the 
equivalent lines in libc/libc.texinfo are:

  * Library Index::

  [...]

  @node Library Index
  @unnumbered Index

Note the "Index" in the unnumbered directive.  Is that a bug in
libc/libc.texinfo, or should libm/libm.texinfo do the same?
