0d643fd3e8 core: change the strip command from a choice to a boolean
Curently, we have a choice to select between stripping and not
stripping. This is legacy code from back when we had a third option,
sstrip (super-strip).

Since we removed sstrip, stripping or not stripping is now just a
boolean rather than a choice.

Make it so.

We make BR2_STRIP_strip default to 'y' to keep the current behaviour of
defaulting to stripping.

Move BR2_STIP_none to legacy, and instruct the user to review the new
setting.

Drop any reference to BR2_STRIP_none in comments.

0f4435e950 core: do not hard-code inclusion of br2-external in Kconfig
Move the inclusion of br2-external's Config.in to the generated kconfig
snippet.

This will ultimately allow us to use more than one br2-external tree.

Offload the "User-provided options" menu to the generated Kconfig
snippet. We can also move the definition of the Kconfig-version of
BR2_EXTERNAL into this snippet.

We introduce an extra check that was not present in the previous code,
to check that we do have permission on that directory. Prevciously, it
was handled as a side effect of not being able to cd into there, but it
is cleaner to check it expressly.

49315f2fac Remove BR2_DEPRECATED
The BR2_DEPRECATED logic is a lot less useful than the legacy handling,
because the symbols just disappears without warning to the user. For
example, we had a few defconfigs that were using deprecated symbols
(which were not actually used because BR2_DEPRECATED wasn't set) so
these didn't build the expected code anymore.

Also, the idea behind BR2_DEPRECATED is that you can easily revive it
again if there is interest. However, it is relatively easy to revert
the removal of a package as well.

The deprecation is also more effort because it has to be removed twice:
once when deprecating, and once when really removing.

It doesn't make sense to add a legacy entry for BR2_DEPRECATED. Users
who actually used it will get legacy warnings instead.

d29c7196bf toolchain: granular choice for stack protector
Currently, we only support two levels of stach-smashing protection:
  - entirely disabled,
  - protect _all_ functions with -fstack-protector-all.

-fstack-protector-all tends to be far too aggressive and impacts
performance too much to be worth on a real product.

Add a choice that allows us to select between different levels of
stack-smashing protection:
  - none
  - basic   (NEW)
  - strong  (NEW)
  - all

The differences are documented in the GCC online documentation:

1e97b27873 ccache: support changing the output directory
When building in a different output directory than the original build,
there will currently be a lot of ccache misses because in many cases
there is some -I/... absolute path in the compilation. Ccache has an
option CCACHE_BASEDIR to substitute absolute paths with relative paths,
so they wil be the same in the hash (and in the output).

Since there are some disadvantages to this path rewriting, it is made
optional as BR2_CCACHE_USE_BASEDIR. It defaults to y because the
usefulness of ccache is severely reduced without this option.

In addition to CCACHE_BASEDIR, we also substitute away the occurences
of $(HOST_DIR) in the calculation of the compiler hash. This is done
regardless of the setting of BR2_CCACHE_USE_BASEDIR because it's
quite harmless.

switch from the existing default of building both shared and static
libraries to building shared libraries only (of course only on
platforms that support shared libraries).

Building both shared and static takes time (since the shared objects
must be built with -fPIC, while static objects are generally built
without, as -fPIC has some performance impact) and consumes a little
bit more disk space.

For example, a static+shared build of libglib2 takes 1 minutes and 59
seconds, with a final build directory of 96 MB. A shared-only build of
libglib2 takes only 1 minutes and 31 seconds (almost a 25% reduction
of the build time), and the final build directory weights 89 MB (a
reduction of almost 8%).

So, switching to a shared library only build brings some useful build
time and build size benefits.

158001f57b Turn the static lib option into a choice with more options
This commit turns the single static option into a choice, which offers
various possibilities:

 1. Build and use static libraries only;
 2. Build both shared and static libraries, but use shared libraries;
 3. Build and use shared libraries only.

On most platforms, (2) is currently the default, and kept as the
default in this commit. Of course, on certain platforms (Blackfin,
m68k), only option (1) will be available.

In addition to the introduction of the Config.in options, this commit
also:

 * Removes the 'select BR2_STATIC_LIBS' from 'BR2_BINFMT_FLAT', since
   with the use of a choice, we are guaranteed that BR2_STATIC_LIBS
   will be selected when the binary format is BR2_BINFMT_FLAT, since
   BR2_STATIC_LIBS will be the only possible solution in the choice.

 * Changes package/Makefile.in to use the proper
   --{enable,disable}-{shared,static} options for autotools packages.

[Thomas: remove useless empty newline right after 'choice'. Noticed by
Yann E. Morin.]
