The current test to verify if the toolchain uses musl or not is based on
checking if /lib/libc.so or /lib/libm.so exist in the sysroot. However,
some toolchains (notably Crosstool-NG ones) put these libraries in
/usr/lib/.
To fix this, build a minimal C program and check if the program
interpreter contains /lib/ld-musl.

TOOLCHAIN_EXTERNAL_READELF is defined to
$(TOOLCHAIN_EXTERNAL_CROSS)readelf$(TOOLCHAIN_EXTERNAL_SUFFIX), where
TOOLCHAIN_EXTERNAL_SUFFIX is .br_real for Buildroot
toolchains. However, this is bogus, because readelf is not wrapped by
the Buildroot toolchain wrapper, so "<arch>-readelf.br_real" never
exists.
Therefore, it should simply be defined as
$(TOOLCHAIN_EXTERNAL_CROSS)readelf. Currently,
TOOLCHAIN_EXTERNAL_READELF is not used anywhere, so it wasn't visible,
but a follow-up commit will make use of it.

Sync external prebuilt toolchain with the one we now build in Buildroot,
i.e. arc-2016.09. Since that prebuilt toolchain finally has IPv6 enabled
it works pretty fine for building packages in Buildroot.
Still note:
1) There might be subtle differences between uClibc configuration
compared to Buildroot's one.
2) A couple of patches we apply on top of Builroot-built toolchain
are obviously missing in the prebuilt version - they will be
available in the next release.

The Linaro toolchains are currently only available on ARMv7-A, but can

This toolchain has many problems which are fixed in contemporary gcc
and uClibc-ng. In addition, several hacks are needed to be able to
work with this toolchain. All these hacks are removed as well. Also
the package exceptions for this toolchain are removed.
The BR2_BFIN_INSTALL_FDPIC_SHARED and BR2_BFIN_INSTALL_FLAT_SHARED
options don't get a legacy entry. For the ADI toolchain, there already
is a legacy entry, so it doesn't make sense to add it twice. For other
external toolchains, these options didn't actually work, because they
rely on the specific layout of the ADI toolchain.

We currently support gcc as old as 4.3. However, Buildroot works
perfectly well with even older gcc versions (tested with 4.1). So we
can add an option BR2_TOOLCHAIN_EXTERNAL_GCC_OLD to support that. The
help text of this option is written with plenty of discouragement.
We use _OLD and not something like _PRE_4_3, because at some point we
will likely remove the 4.3 option and what would then require a name
change.
We don't set any _AT_LEAST option in this case because it's no use -
there is no lower bound on the version in this case. We therefore leave
BR2_TOOLCHAIN_GCC_AT_LEAST empty (the implicit default). When it is
empty, we don't do a version check at all in check_gcc_version
(previously we errored out when it was empty).

The toolchain-external-package infrastructure is just a copy of the
toolchain-external commands, replacing TOOLCHAIN_EXTERNAL by $(2)
and adding double-dollars everywhere.
toolchain-external itself is converted to a virtual package, but it
is faked a little to make sue the toolchains that haven't been
converted to toolchain-external-package yet keep on working.
The TOOLCHAIN_EXTERNAL_MOVE commands don't have to be redefined
for every toolchain-external-package instance, so that is moved
out into the common part of pkg-toolchain-external.mk.
The musl-compat-headers dependency stays in the toolchain-external
package itself.
The musl ld link is duplicated in the legacy toolchain-external and
the toolchain-external-package, because they have separate hooks.
The handling of TOOLCHAIN_EXTERNAL_BIN deserves some special attention,
because its value will be different for different
toolchain-external-package instances. However, the value only depends
on variables that are set by Kconfig (BR2_TOOLCHAIN_EXTERNAL_PREFIX
and BR2_TOOLCHAIN_EXTERNAL_DOWNLOAD) so it can easily be used in
the generic part. So we don't have to do anything specific for this
variable after all.
