#     kbuild: clean up ${quiet} checks in shell scripts
#     
#     There were efforts to make 'make -s' really silent when it is a
#     warning-free build.
#     
#     The conventional way was to let a shell script check ${quiet}, and if
#     it is 'silent_', suppress the stdout by itself.
#     
#     With the previous commit, the 'cmd' takes care of it now. The 'cmd' is
#     also invoked from if_changed, if_changed_dep, and if_changed_rule.
#     
#     You can omit ${quiet} checks in shell scripts when they are invoked
#     from the 'cmd' macro.
