8442ae7946 crosstool-ng: Use same naming convention as internal toolchains
Use unknown for the vendor part of the tuple, and add $arch-linux- symlinks,
similar to how it's done for the internal toolchain, rather than using
buildroot_ctng and unknown symlinks.

5c09e36cb6 toolchain: more verbose in crosstool-ng backend
By default, Crosstool-NG hides all the details of the toolchain build
process. However, this is inconsistent with the typical Buildroot
build, and the rotating progress thing makes log file resulting from
redirecting the Buildroot output a bit unusable. Therefore, switch the
Crosstool-NG configuration to a more verbose default.

6b578c8d73 toolchain: rework C++ options
Instead of having BR2_GCC_CROSS_CXX and BR2_INSTALL_LIBSTDCPP, with
BR2_GCC_CROSS_CXX not being visible (and therefore being useless),
let's just keep BR2_INSTALL_LIBSTDCPP to enable C++ in the toolchain
and install C++ libraries on the target.

We also take that opportunity to make BR2_INSTALL_LIBSTDCPP an hidden
option, which is selected by an option in Buildroot toolchain support
or an option in External toolchain support, just as we did for other
toolchain features.

Some work definitely remains to be done :

 - The name BR2_INSTALL_LIBSTDCPP is ugly, but we keep it for the
   moment in order to avoid changing all packages.

 - We should clarify the other language-related options (Fortran,
   Java, Objective-C, etc.).

01b434b27a toolchain: remove toolchain-specific stripping
We already handle the stripping of libraries in $(TARGET_DIR) at the
global level, so there's no need to have toolchain-specific option and
code for this.

fff711786a toolchain: Improve C library option selection
Turn BR2_LARGEFILE, BR2_INET_IPV6, BR2_INET_RPC, BR2_USE_WCHAR,
BR2_ENABLE_LOCALE and BR2_PROGRAM_INVOCATION into hidden options.

Then, for Buildroot toolchains, external toolchains and Crosstool-NG
toolchains, provide visible options that selects the hidden options.

This allows :

 * To show a different label and help text in the case of Buildroot
   toolchain (do you want to enable feature X ?) and in the case of
   external toolchain (is feature X available in your toolchain ?)

 * To not show any option when a glibc external toolchain is selected
   (since glibc is assumed to support all of largefile, IPv6, RPC,
   WCHAR, locale and program invocation) and have them all selected in
   that case.

There is some amount of duplication between Buildroot toolchain config
options and Crosstool-NG toolchain config options, because kconfig
doesn't allow to source the same Config.in file twice (even if under
mutually exclusive conditions). This duplication is more readable that
the hack that consists in splitting files in multiple pieces.

However, this commit changes the name of the options visible in the
configuration interface, so existing .config files will have to be
updated accordingly.

72568d543b toolchain/crosstool-NG: add C library config munging
For some C libraries, it can be necessary to push the BR settings
down to the libc configuration file. Prepare the infrastructure.

(Note: it will apply only to uClibc for now, and although eglibc
can also be configured, it is not currently supported)
