loadable app support
* apps: Introduce a build system for loadable apps for nsh.
This PR consits of following changes. (NOTE: Changes to each
application will be provided separately)
apps/nshlib/Kconfig:
Add 'option modules' to NSH_FILE_APPS so that a user can change
an application configuration to tristate (y/n/m)
apps/Make.defs:
Override COMPILE and COMPILEXX macros to compile loadable apps.
To make loadable apps, -DLOADABLE_APP is added to the flags.
Also, introduce ELFLD to link a lodable app.
Please note that the variable 'LOADABLE' must be defined in
each application Makefile if you want to make a loadable app.
apps/Application.mk:
Add .build target in case of 'LOADABLE=y' which is used to
link a final loadable application and install the app to
apps/bin.
apps/Makefile:
Add SYMTABSRC and SYMTABOBJ variables for loadable apps which
will be generated under the apps directory.
Add make_symbols target which will be called when all applications
are installed to generate symtab_app.c which is used for
nsh to inform symbol information to the NuttX kernel.

* apps/examples/hello: Apply changes to support a lodable app.
Kconfig:
Change the application state from bool to tristate
Make.defs:
Change the condition to build. By default, the application is
not selected (i.e. 'n'), so if other states (i.e. y/m) are
selected, the application will be compiled.
Makefile:
If the application is specified to 'm', the variable 'LOADABLE'
must be defined here. Also note that other variables (PRIORITY
and STACKSIZE) can only be used for built-in apps.
hello_main.c
Add LOADABLE_APP condition to main().
