- Force a rebuild if a script in applets_sh is changed.
- Move the dummy usage messages for custom applets to usage.h and
change the name from 'dummy' to 'scripted'.
- Hide an error from gen_build_files.sh if an embed directory exists
but is empty.
- Tidy up embedded_scripts script.
v2: Remove a couple of unnecessary tests in embedded_scripts, as
pointed out by Xabier Oneca.
Drop the stripping of comments.

The build process for embedded scripts didn't have consistent
support for saving output to a different directory.

BusyBox has support for embedded shell scripts. Two types can be
distinguished: custom scripts and scripts implementing applets.
Custom scripts should be placed in the 'embed' directory at build
time. They are given a default applet configuration and appear
as applets to the user but no further configuration is possible.
Applet scripts are integrated with the BusyBox build system and
are intended to be used to ship standard applets that just happen
to be implemented as scripts. They can be configured at build time
and appear just like native applets.
Such scripts should be placed in the 'applets_sh' directory. A stub
C program should be written to provide the usual applet configuration
details and placed in a suitable subsystem directory. It may be
helpful to have a configuration option to enable any dependencies the
script requires: see the 'nologin' applet for an example.

To assist in the deployment of shell scripts it may be convenient
to embed them in the BusyBox binary.
'Embed scripts in the binary' takes any files in the directory
'embed', concatenates them with null separators, compresses them
and embeds them in the binary.
When scripts are embedded in the binary, scripts can be run as
'busybox SCRIPT [ARGS]' or by usual (sym)link mechanism.
embed/nologin is provided as an example.

The files generated by the include/config/MARKER target are in the
dependency list for applets/applet_tables.
If applets/applet_tables is created first during applets_dir then it will
be created again later as part of $(busybox-dirs).
As a result include/applet_tables.h is created again. This time while other
build commands may need it.
Let applets_dir depend on include/config/MARKER to avoid this particular
race condition and create the header files atomically to ensure that the
compiler never sees incomplete files.

Makefile.flags contains:
ARCH_FPIC ?= -fpic
ARCH_FPIE ?= -fpie
However, arch/$(ARCH)/Makefile gets included *after* Makefile.flags,
and therefore doesn't get the chance to provide its own value.
Fix this by including arch/$(ARCH)/Makefile *before* Makefile.flags.

This target doesn't work with current directory layout. Just make cscope
index all .c and .h files.
While we're at it: add cscope output files to .gitignore.

Newer versions of libselinux has started linking against more libs.
Rather than continuing hardcoding things, switch to using pkg-config
to query for its dependencies.

to *_defconfig. 'make xyz_defconfig' will enable the
