	basesrc/usr.bin/make: compat.c job.c job.h main.c make.1 make.h parse.c
	    var.c

Log Message:
A number of semi-related changes.
1. make -dx turns on DEBUG_SHELL which causes sh -x to be used where
   possible.
2. PrintOnError() is now called when make is stopping due to an error.
   This routine reports the curdir and the value of any variables listed
   in MAKE_PRINT_VAR_ON_ERROR.
3. Variables set via command line, are propagated to child-makes via
   MAKEFLAGS.  This behaviour appears to be necessary for POSIX (according
   to the GNU folk anyway).
4. Do not reset MAKEFILE when reading ".depend" as this rather eliminates the
   usefulness of ${MAKEFILE}.
5. Added ${.newline} as a simple means of being able to include \n in the
   result of a :@ loop expansion.
6. Set ${MAKE_VERSION} if defined.  Need to come up with a useful value.
