Import bmake-20200902 Lots of code refactoring, simplification and cleanup. Lots of new unit-tests providing much higher code coverage. All courtesy of rillig at netbsd. Other significant changes: o new read-only variable .SHELL which provides the path of the shell used to run scripts (as defined by the .SHELL target). o new debug option -dl: LINT mode, does the equivalent of := for all variable assignments so that file and line number are reported for variable parse errors. 2020-09-05 16:11:04 +00:00			`# $Id: host-target.mk,v 1.13 2020/08/05 23:32:08 sjg Exp $`
