Here are the test cases I used for developing the text expansion feature. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

'info' prints the argument to stdout.
$(info,hello world 0)
'warning-if', if the first argument is y, sends the second argument to stderr,
and the message is prefixed with the current file name and line number.
$(warning-if,y,hello world 1)
'error-if' is similar, but it terminates the parsing immediately.
The following is just no-op since the first argument is not y.
$(error-if,n,this should not be printed)
Shorthand
warning = $(warning-if,y,$(1))
'shell' executes a command, and returns its stdout.
$(warning,$(shell,echo hello world 3))
Every newline in the output is replaced with a space,
but any trailing newlines are deleted.
$(warning,$(shell,printf 'hello\nworld\n\n4\n\n\n'))
'filename' is expanded to the currently parsed file name,
'lineno' to the line number.
$(warning,filename=$(filename)) $(warning,lineno=$(lineno))
