René Kijewski 9a15a6def5 make: easify {sys,drivers}/Makefile
Currently you need to add every new sys and driver module into the
respective Makefile. This requires rebasing if another module was merged
in the meantime.

This PR allows you to omit the entry to {sys,drivers}/Makefile, if the
subfolder has the same name as the module name, which should be sensible
in most cases.

Ludwig Ortmann 182b603a01 make: 1571 fixup: dont create existing directories
This fixes an error which was introduced by commit

The timestamp of directories is updated when a file inside a directory
is changed.
Therefore, make decides a target needs to be rebuilt, whenever that
target depends on its parent directory, because the directory is
always newer than the file inside.

    Occasionally, however, you have a situation where you want to
    impose a specific ordering on the rules to be invoked without
    forcing the target to be updated if one of those rules is
    executed. In that case, you want to define order-only
    prerequisites. Order-only prerequisites can be specified by
    placing a pipe symbol (|) in the prerequisites list: any
    prerequisites to the left of the pipe symbol are normal; any
    prerequisites to the right are order-only:

         targets : normal-prerequisites | order-only-prerequisites

René Kijewski 35e74ad725 make: refactor make system (parallelism, deduplication)
Almost everything was build sequentially in RIOT, because we employed
explicit for-loops to build directories (DIRS). This PR makes our make
system use normal dependencies to build directories.

All our compiling rules were duplicated, once for the application, once
for modules. This PR makes the application a normal module, removing
this duplication.

René Kijewski 467b41ad49 make: easifier usage of module subdirectories
Many modules have subdirectories. Often these subdirectories should only
be included under certain circumstances. Modules that use submodules
currently need to use this pattern:

DIRS = …

all: $(BINDIR)$(MODULE).a
   @for i in $(DIRS) ; do $(MAKE) -C $$i ; done ;

include $(RIOTBASE)/Makefile.base

   @for i in $(DIRS) ; do $(MAKE) -C $$i clean ; done ;

This PR moves the `all:` and `clean::` boilerplate into `Makefile.base`.

René Kijewski 840c0f0a57 make: detect their module name automatically
For many modules the `Makefile` contains a line like
MODULE:=$(shell basename $(CURDIR))
This conclusively shows that we do not have to set the module name

This PR removes the need to set the module name manually, if it is the
same as the basename. E.g. for `…/sys/vtimer/Makefile` the variable
make `MODULE` will still be `vtimer`, because it is the basename of the

Make: exterminate 'clean' buildtarget clutter

René Kijewski 300d6b3e35 Make: exterminate 'clean' buildtarget
Closes #993.

We do not need to descend into the modules to know what to do on
`make clean BOARD=blub`. We can just invoke `rm -rf bin/blub`.

This PR only keeps the descending into the USEPKGs, since they might
want to delete cached/downloaded/extracted data.

René Kijewski 3f59eefbaf Use subfolders in bin dir
Creating all object files in one directory is bound to produce name
clashes. RIOT developers may take care to use unique file names, but
external packages surely don't.

With this change all the objects of a module (e.g. `shell`) will be
created in `bin/$(BOARD)/$(MODULE)`.

I compared the final linker command before and after the change. The
`.o` files (e.g. `startup.o`, `syscall.o` ...) are included in the same
order. Neglecting the changed path name where the `.o` files reside, the
linker command stays exactly the same.

A major problem could be third party boards, because the location of the
`startup.o` needs to the specified now in
`boards/$(BOARD)/Makefile.include`, e.g.
export UNDEF += $(BINDIR)msp430_common/startup.o
