Create 'obj' directory in current directory instead a symbolic link to the 'obj' tree if defined. [not set] Print a warning if 'obj' tree (/usr/obj) does not exist. Change default 'obj' directory from ``obj.${MACHINE}'' back to ``obj'', unfortunately many Makefiles are wired with the name ``obj''. Add some comments for variables and targets.
