e2e4950b2d toolchain: use same gdb Config.in for internal/external toolchains
We used to use different gdb configs for internal and external toolchains
because mconf won't source the same file twice. This works, but is kind of
sub optimal, as people forget to keep them in sync.

Fix it to use the same file for both situations by shuffling around the
config options a bit. Should work identical to before (except for the newer
gdb versions available for ext).

51f5f62754 External toolchain support improvements
Improve external toolchain support

 * Do not put kernel-headers in the dependencies of BASE_TARGETS in
   the case where BR2_TOOLCHAIN_SOURCE is not y. The kernel headers
   are already supposed to be part of the external toolchain, so
   there's no need to download, extract and install them.

 * In the configuration system, don't display the kernel headers
   version selection list when an external toolchain is selected. This
   is implemented by moving the source
   "toolchain/kernel-headers/Config.in" inside the if
   BR2_TOOLCHAIN_SOURCE in toolchain/Config.in.2.

 * Change the description and help message of the BR2_LARGEFILE,
   BR2_INET_IPV6, BR2_INET_RPC, and BR2_SOFT_FLOAT option in
   toolchain/external-toolchain/Config.in. In the case of an external
   toolchain, the semantic of these options is not to enable large
   file support, IPV6 or RPC (since the toolchain is already compiled,
   it has been decided previously). Their semantic is to let Buildroot
   know about the characteristics of the external toolchain being
   used.

   As an improvement, we could guess these values automatically:

    - for BR2_LARGEFILE, look at the value of __UCLIBC_HAS_LFS__ in
      bits/uClibc_config.h in the libc headers directory.

    - for BR2_INET_RPC, look at the value of __UCLIBC_HAS_RPC__ in the
      same file

    - for BR2_INET_IPV6, look at the value of __UCLIBC_HAS_IPV6__ in
      the same file

    - for BR2_SOFT_FLOAT, look at the output of $(CC) -v 2>&1 | grep
      -- "--with-float=soft"

   But I'm not sure how this would be possible, since these values are
   used at configuration-time by other configuration options, not only
   at build time.

4683420c4c Kconfig: remove 'default n'
'default n' is the default, so there's no need to say it explicitly.

f85cd12c17 toolchain: also setup kernel headers when ext toolchain is used
Provide kernel headers when ext toolchain is used, so we can compile
packages which need them.
