This commit adds support for external toolchains based on the musl C
library, as available from http://www.musl-libc.org.
Note that the pre-built musl toolchains available from
http://musl.codu.org/ are not working for the moment, since they lack
sysroot support. However, this problem has been reported to the
maintainer, who has already added sysroot support in his scripts at
https://bitbucket.org/GregorR/musl-cross, and therefore the next
version of the pre-built toolchains should work with Buildroot
out-of-the-box. In the mean time, the musl-cross script must be used
to build the toolchain.

The check_glibc function contained checks to verify that the user had
properly enabled the largefile, IPv6, locale and wchar options, to
match how glibc is configured. This was useful when the support for
glibc external toolchains was introduced, but since then, we added the
BR2_TOOLCHAIN_USES_GLIBC symbol that automatically enables largefile,
IPv6, locale and wchar support when a glibc or eglibc external
toolchain is used. Therefore, many of the check_glibc checks are
useless now, so we can remove these.

This commit fixes various typos and mistakes in the comment at the top
of the helpers.mk file:
* usefull -> useful
* The optional stripping of libraries no longer exists, so there's no
reason to mention it.
* Indicate that the copy_toolchain_lib_root function is also used by
the glibc package, not only by the external toolchain logic.
* Separate more clearly the top comment introducing the entire file,
from the comment introducing the first function.

Until now, the copy_toolchain_lib_root function took as argument the
base name of a library (e.g: libm.so), and was assuming that the usual
scheme libm.so.<x> being a symbolic link to the real library was used.
However, with musl based toolchains, the C library is named libc.so
directly, with no symbolic link at all. Therefore, this commit changes
the copy_toolchain_lib_root to move the responsibility of using a
wildcard or not after the library name the caller's responsibility.
So, all the existing LIB_EXTERNAL_LIBS values are modified to have a
.* at the end, so that the behavior is effectively unchanged.

The external toolchain code makes the assumption that all C libraries
have a ld*.so, libc.so, libcrypt.so, libdl.so, libgcc_s.so, libm.so,
libnsl.so, libresolv.so, libutil.so, and when thread support is
enabled, libpthread.so, etc.
However, this is not the case with the musl C library, which
integrates all the functionalities in a single libc.so file. In
preparation of the support of the musl library, we make the current
value of LIB_EXTERNAL_LIBS conditional to glibc or uClibc.
The addition of additional libraries through
BR2_TOOLCHAIN_EXTRA_EXTERNAL_LIBS is kept outside the condition, at
the end.

This commit converts the 'toolchain-external' logic to the package
infrastructure.
The TOOLCHAIN_EXTERNAL_DIR variable (which points to where the
toolchain is located) is renamed to TOOLCHAIN_EXTERNAL_INSTALL_DIR,
because the former conflicts with the package infrastructure (which
defines the <pkg>_DIR variable for each package as pointing to its
build directory).
The new _EXTRA_DOWNLOADS mechanism is used for Blackfin toolchains.
The extract, configuration and installation steps are converted inside
the <pkg>_EXTRACT_CMDS, <pkg>_CONFIGURE_CMDS and
<pkg>_INSTALL_STAGING_CMDS.

This commit converts the toolchain-buildroot logic to the package
infrastructure. The package is fairly simple as it only defines
BUILDROOT_LIBC, and depends on host-gcc-final to get the overall
internal toolchain build logic started.

This commit introduces a virtual package called 'toolchain', located
in 'toolchain/toolchain', which simply depends on
'toolchain-buildroot' or 'toolchain-external' depending on the
selected toolchain backend.
For now, toolchain-buildroot and toolchain-external are still manual
make targets, but the following patches convert those backends to use
the package infrastructure as well.
In addition to this:
* The main Makefile is modified to always make BASE_TARGETS point to
this new toolchain virtual package.
* The main Makefile is changed to include all the toolchain/*/*.mk
files: the toolchain virtual package, and the toolchain-buildroot
and toolchain-external directories.
* The dependency of the toolchain on prepare dirs and dependencies is
moved to the toolchain virtual package. It is moved as a
prerequisite of the "toolchain-source" rule to ensure that all
directories are prepared before we even start extracting the
toolchain.

Converting the external toolchain logic into a package raises a very
special use case that wasn't handled by the package infrastructure:
the Blackfin toolchain is delivered as two tarballs instead of
one. Unfortunately <pkg>_SOURCE only allows to pass one tarball name.
However, we really want both tarballs to be known by the package
infrastructure, so that the normal 'source' and 'external-deps'
mechanism work fine.
In order to achieve this, we add a <pkg>_EXTRA_DOWNLOADS variable,
which allows a package to list other stuff it would like to see
downloaded, but that are otherwise not used by the package
infrastructure itself: it is up to the package to do it by itself.

The stubs.h header is not installed by install-headers, but is needed
for the gcc build. An empty stubs.h will work, as explained in
http://gcc.gnu.org/ml/gcc/2002-01/msg00900.html. The same trick is
used by Crosstool-NG.

Until now, only the eglibc build was pulling host-gawk as a

also requires host-gawk.

With the 1.0.26 version bump a new routine was added to find newer
versions of ffmpeg and/or libav on different include paths.
Unfortunately this uses absolute pathnames hence when there's no
matching ffmpeg/libav headers on the host it fails to build. Fixes:
