The last change added .PRECIOUS: $(BIN) to everyway Makefile in hopes the libapps.a will not be deleted on Control-C (unproven so far).  However, $(BIN) may contain back slashes in some build platforms and that causes problems for make:  It can't handle the backslashes in the .PRECIOUS dependency list.  $(BIN) replaced with ../../libapp.a, where the number of ../ depends on the depth of the Makefile in the apps/ source tree.

All Makefiles:  Add .PRECIOUS: apps/libapps.a to every Makefile.  Hopefully this will end awkward problems when you Control-C out of a build and libapps.a is deleted.

Bitbucket Issue 5, apps build system: The previous patch wasn't complete, it was just idea how to resolve issue.  Please, find attached issue5.patch to resolve it. It can be applied on top current apps/master. From Artur Mądrzak.

Add the dirlinks target to some Makefiles.  This plugs some wholes open by last chicken-and-egg build fix

apps/tools/mkkconfig.sh:  The top-level Kconfig file is not auto-generated.  The autogenerated Kconfig file will be constructed so that every second level directory that contains a Kconfig file will automatically be sourced

Build-server sometimes fails 'make -j24' with:

 In file included from builtin_list.c:62:0:
 builtin_list.h:1:46: error: 'ts_engine_main' undeclared here (not in a function)
  { "ts_engine", SCHED_PRIORITY_DEFAULT, 2048, ts_engine_main },

or sometimes silently succeeds but generates builds that contain
a random subset of configured NuttX applications. There are two
root causes for this:

1) Recipes for building builtin_list.h and builtin_proto.h are not
   linearizable.
2) Nothing ensures that 'make context' is run first for apps/builtin

This patch addresses both issues.

Add an install target to all makefiles.  For the import build, the top-level Makefile now does two passes: (1) builds libapp.a, then (2) installs the programs (not yet finished)

Beginning of logic that will, hopefully, all me to build applications against a NuttX export package (vs. the nuttx/ source tree).

apps/Makefile should include external/Make.defs so that external applications can participate in the menu configuration

Remove some dependencies of distclean on clean.  This should not be necessary in higher level makefiles and should speed up make distclean
