Yann E. MORIN e6d1a2073b toolchain/external: newer Linaro toolchains do not provide source code 
Currently, we have a pattern-matching that automatically derives the
the source tarball filename from the binary tarball filename.

However, the latest Linaro toolchains no longer follow that scheme (and
do not even readily provide the sources...).

Remove the generic pattern-matching, and explicitly set the source
tarball name for those toolchains that do have a source tarball readily
available.

################################################################################
#
# This package implements the support for external toolchains, i.e
# toolchains that are available pre-built, ready to use. Such toolchain
# may either be readily available on the Web (Linaro, Sourcery
# CodeBench, from processor vendors) or may be built with tools like
# Crosstool-NG or Buildroot itself. So far, we have tested this
# with:
#
# * Toolchains generated by Crosstool-NG
# * Toolchains generated by Buildroot
# * Toolchains provided by Linaro for the ARM and AArch64
# architectures
# * Sourcery CodeBench toolchains (from Mentor Graphics) for the ARM,
# MIPS, PowerPC, x86, x86_64 and NIOS 2 architectures. For the MIPS
# toolchain, the -muclibc variant isn't supported yet, only the
# default glibc-based variant is.
# * Analog Devices toolchains for the Blackfin architecture
# * Xilinx toolchains for the Microblaze architecture
# * Synopsys DesignWare toolchains for ARC cores
#
# The basic principle is the following
#
# 1. If the toolchain is not pre-installed, download and extract it
# in $(TOOLCHAIN_EXTERNAL_INSTALL_DIR). Otherwise,
# $(TOOLCHAIN_EXTERNAL_INSTALL_DIR) points to were the toolchain has
# already been installed by the user.
#
# 2. For all external toolchains, perform some checks on the
# conformity between the toolchain configuration described in the
# Buildroot menuconfig system, and the real configuration of the
# external toolchain. This is for example important to make sure that
# the Buildroot configuration system knows whether the toolchain
# supports RPC, IPv6, locales, large files, etc. Unfortunately, these
# things cannot be detected automatically, since the value of these
# options (such as BR2_TOOLCHAIN_HAS_NATIVE_RPC) are needed at
# configuration time because these options are used as dependencies
# for other options. And at configuration time, we are not able to
# retrieve the external toolchain configuration.
#
# 3. Copy the libraries needed at runtime to the target directory,
# $(TARGET_DIR). Obviously, things such as the C library, the dynamic
# loader and a few other utility libraries are needed if dynamic
# applications are to be executed on the target system.
#
# 4. Copy the libraries and headers to the staging directory. This
# will allow all further calls to gcc to be made using --sysroot
# $(STAGING_DIR), which greatly simplifies the compilation of the
# packages when using external toolchains. So in the end, only the
# cross-compiler binaries remains external, all libraries and headers
# are imported into the Buildroot tree.
#
# 5. Build a toolchain wrapper which executes the external toolchain
# with a number of arguments (sysroot/march/mtune/..) hardcoded,
# so we're sure the correct configuration is always used and the
# toolchain behaves similar to an internal toolchain.
# This toolchain wrapper and symlinks are installed into
# $(HOST_DIR)/usr/bin like for the internal toolchains, and the rest
# of Buildroot is handled identical for the 2 toolchain types.

# Details about sysroot directory selection.
#
# To find the sysroot directory, we use the trick of looking for the
# 'libc.a' file with the -print-file-name gcc option, and then
# mangling the path to find the base directory of the sysroot.
#
# Note that we do not use the -print-sysroot option, because it is
# only available since gcc 4.4.x, and we only recently dropped support
# for 4.2.x and 4.3.x.
#
# When doing this, we don't pass any option to gcc that could select a
# multilib variant (such as -march) as we want the "main" sysroot,
# which contains all variants of the C library in the case of multilib
# toolchains. We use the TARGET_CC_NO_SYSROOT variable, which is the
# path of the cross-compiler, without the --sysroot=$(STAGING_DIR),
# since what we want to find is the location of the original toolchain
# sysroot. This "main" sysroot directory is stored in SYSROOT_DIR.
#
# Then, multilib toolchains are a little bit more complicated, since
# they in fact have multiple sysroots, one for each variant supported
# by the toolchain. So we need to find the particular sysroot we're
# interested in.
#
# To do so, we ask the compiler where its sysroot is by passing all
# flags (including -march and al.), except the --sysroot flag since we
# want to the compiler to tell us where its original sysroot
# is. ARCH_SUBDIR will contain the subdirectory, in the main
# SYSROOT_DIR, that corresponds to the selected architecture
# variant. ARCH_SYSROOT_DIR will contain the full path to this
# location.
#
# One might wonder why we don't just bother with ARCH_SYSROOT_DIR. The
# fact is that in multilib toolchains, the header files are often only
# present in the main sysroot, and only the libraries are available in
# each variant-specific sysroot directory.

#

# LIBC_A_LOCATION: location of the libc.a file in the default
# multilib variant (allows to find the main
# sysroot directory)
# Ex: /x-tools/mips-2011.03/mips-linux-gnu/libc/usr/lib/libc.a
#
# SYSROOT_DIR: the main sysroot directory, deduced from
# LIBC_A_LOCATION by removing the
# usr/lib[32|64]/libc.a part of the path.
# Ex: /x-tools/mips-2011.03/mips-linux-gnu/libc/
#
# ARCH_LIBC_A_LOCATION: location of the libc.a file in the selected
# multilib variant (taking into account the
# CFLAGS). Allows to find the sysroot of the
# selected multilib variant.
# Ex: /x-tools/mips-2011.03/mips-linux-gnu/libc/mips16/soft-float/el/usr/lib/libc.a
#
# ARCH_SYSROOT_DIR: the sysroot of the selected multilib variant,
# deduced from ARCH_LIBC_A_LOCATION by removing
# usr/lib[32|64]/libc.a at the end of the path.
# Ex: /x-tools/mips-2011.03/mips-linux-gnu/libc/mips16/soft-float/el/
#
# ARCH_LIB_DIR: 'lib', 'lib32' or 'lib64' depending on where libraries
# are stored. Deduced from ARCH_LIBC_A_LOCATION by
# looking at usr/lib??/libc.a.
# Ex: lib
#
# ARCH_SUBDIR: the relative location of the sysroot of the selected
# multilib variant compared to the main sysroot.
# Ex: mips16/soft-float/el
#
# SUPPORT_LIB_DIR: some toolchains, such as recent Linaro toolchains,
# store GCC support libraries (libstdc++,
# libgcc_s, etc.) outside of the sysroot. In
# this case, SUPPORT_LIB_DIR is set to a
# non-empty value, and points to the directory
# where these support libraries are
# available. Those libraries will be copied to
# our sysroot, and the directory will also be
# considered when searching libraries for copy
