newlib: libc: move manual into top-level build

This doesn't migrate all the docs, just the libc's manual (pdf/info).
This is to show the basic form of migrating the chew files.

For subdirs that didn't have any docs, I've stripped their settings
for clarity.  If someone wanted to suddenly add docs, they can add
the corresponding Makefile.inc files easily.
