Variables defined with `=' are recursively expanded variables. Variables defined with `:=' are simply expanded variables;

foo = $(bar)
bar = $(ugh)
ugh = Huh?

all:;echo $(foo)

will echo `Huh?': `$(foo)' expands to `$(bar)' which expands to `$(ugh)' which finally expands to `Huh?'.

CFLAGS = $(include_dirs) -O
include_dirs = -Ifoo -Ibar

will do what was intended: when `CFLAGS' is expanded in a command, it will expand to `-Ifoo -Ibar -O'. 

CFLAGS = $(CFLAGS) -O

because it will cause an infinite loop in the variable expansion. (Actually make detects the infinite loop and reports an error.)

MAKECMDGOALS: The targets given to make on the command line. Setting this variable has no effect on the operation of make.
If an included makefile cannot be found in any of these directories, a warning message is generated, but it is not an immediately fatal error; processing of the makefile containing the include continues. Once it has finished reading makefiles, make will try to remake any that are out of date or don't exist. See section How Makefiles Are Remade. Only after it has tried to find a way to remake a makefile and failed, will make diagnose the missing makefile as a fatal error.

If you want make to simply ignore a makefile which does not exist and cannot be remade, with no error message, use the -include directive instead of include, like this:

 	

-include filenames...

This acts like include in every way except that there is no error (not even a warning) if any of the filenames do not exist.

TARGET_OPTIMIZATION:=$(BR2_TARGET_OPTIMIZATION) (-Os -pipe)

 * -Os 
Optimize for size.  -Os enables all -O2 optimizations that do not
typically increase code size.  It also performs further optimiza-
tions designed to reduce code size.

-Os disables the following optimization flags: -falign-functions
-falign-jumps  -falign-loops -falign-labels  -freorder-blocks
-freorder-blocks-and-partition -fprefetch-loop-arrays

If you use multiple -O options, with or without level numbers, the
last such option is the one that is effective.

 * -pipe : For a big program involving a lot of inter linked files and functions, temporary files tend to get created while compilation. When this option is specified, the compiler makes use of pipes rather than creating temporary files. The output of each function is piped to the next. The swap space is used instead.

Specifies the number of jobs (commands) to run simultaneously.  If
there  is  more than one -j option, the last one is effective.  If
the -j option is given without an argument, make  will  not  limit
the number of jobs that can run simultaneously.

$(subst from,to,text)
    Performs a textual replacement on the text text: each occurrence of from is replaced by to. The result is substituted for the function call.
$(patsubst pattern,replacement,text)
    Finds whitespace-separated words in text that match pattern and replaces them with replacement. Here pattern may contain a `%' which acts as a wildcard, matching any number of any characters within a word. If replacement also contains a `%', the `%' is replaced by the text that matched the `%' in pattern. Only the first `%' in the pattern and replacement is treated this way; any subsequent `%' is unchanged.

A phony target is one that is not really the name of a file. It is just a name for some commands to be executed when you make an explicit request. There are two reasons to use a phony target: to avoid a conflict with a file of the same name, and to improve performance.

If you write a rule whose commands will not create the target file, the commands will be executed every time the target comes up for remaking. Here is an example:

 	

clean:
        rm *.o temp

Because the rm command does not create a file named `clean', probably no such file will ever exist. Therefore, the rm command will be executed every time you say `make clean'.

The phony target will cease to work if anything ever does create a file named `clean' in this directory. Since it has no prerequisites, the file `clean' would inevitably be considered up to date, and its commands would not be executed. To avoid this problem, you can explicitly declare the target to be phony, using the special target .PHONY (see section Special Built-in Target Names) as follows:

 	

.PHONY : clean

Once this is done, `make clean' will run the commands regardless of whether there is a file named `clean'.
