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]
(From yocto-docs rev: dd785777834611d94868a3774f2eb21ffc081b1a)
