[PATCH] Fix info directory entry

[Jon TURNEY]

I have no clue about info pages, but the attached patch seems to be 
needed for 'info libc' and 'info libm' to work as expected, after the 
newlib info has been installed using install-info.

Subject: [PATCH] Fix newlib texinfo source so 'info libc' and 'info libm' work

If the newlib .info files are installed using install-info, 'info libc' and
'info libm' don't work.

This seems to be due to the formatting of the directory entry line not being
quite right, so fix that.

Also use @direntry texinfo command, rather than writing .info directory entry
literally.

Also use @dircategory texinfo command to place into 'Newlib' category, rather
than ending up in 'Miscellaneous'
