r312452-r312512:
- Use SRCTOP-relative paths to other directories instead of .CURDIR-relative ones
This simplifies pathing in make/displayed output
- Use .CURDIR:H instead of .CURDIR to simplify pathing in output, etc
This both avoids some dependencies on xinstall.host and allows
bootstrapping on older releases to work due to lack of at least 'install -l'
support.

WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.
Still need to add real targets under targets/ to build packages.
