adt-manual, ref-manual: Review edits for xcross-toolchain additions.

Mark Hatle reviewed the section and I updated some things based
off his input.  A rewrite to the "Makefile-Based Projects" section
to get it technically correct.  Also, removed all SDKROOT
documentation from both the adt-manual and ref-manual.

Fixes [YOCTO #7133]
