Log Message:
BUILDING: update from canonical mk.conf(5)

Incorporate content and styles updates for mk.conf entries
from share/man/man5/mk.conf.5, which is the canonical
reference for mk.conf.

Add: BSDOBJDIR, BSDSRCDIR, EXTERNAL_TOOLCHAIN, MKDEBUGKERNEL,
MKDEBUGTOOLS, MKHTML, MKLINKLIB, MKOBJDIRS, TOOLCHAIN_MISSING,
NETBSDSRCDIR

It's for further study as to whether we just replace the
most of subsection "make" variables with a link to mk.conf(5).

Style:
- Add more .de macros per mk.conf.5.
- Order list items alphabetically. When multiple items are present
  in a list item, sort within the item first.
- More cross-references.
