This patch introduces a distro feature which enables gcc to produce
both 32bit and 64bit code, and enables binutils to operate on both
32bit and 64bit binaries. It differs from multilib toolchains in
that it does not require to compile a version of the libc for each
architecture variant. However, the code produced for the secondary
architecture will not be linkable against the libc.
v2: - Renamed the feature name from "biarch" to "multiarch". The GCC
installation manual claims that the mips-linux can be made a tri-arch
compiler (http://gcc.gnu.org/install/configure.html)
- For x86_64, the compiler is made bi-arch by default, so nothing
has to be done in particular.
- I analyzed the gcc/config.gcc from GCC sources and added in this
patch all the architectures that could be made biarch with the version
of gcc currently used in OE, which are powerpc, and sparc, in addition
to x86. mips and s390 will probably be supported in future versions of
gcc. For x86 and sparc, only the --enable-targets=all option is valid
to make this work (this option doesn't have any other side effects than
making the compiler bi-arch). For powerpc, I used the
--enable-targets=powerpc64 option (although 'all' also works).
Note: - Untested on powerpc and sparc. But I believe it works the same
as with x86.
- gcc in meta-toolchain is also made multiarch.

Without this, compiler errors such as:
configure:33440: i586-poky-linux-gcc -march=i586 --sysroot=/media/build2/builds/rptest/b2/tmp/sysroots/qemux86 -o conftest -D_REENTRANT -Wl,-O1 -Wl,--as-needed conftest.c -lpthread >&5

can be see. This is due to the compiler being built against the system
zlib, before zlib-native is built and in the sysroot. Once that has been
built it can confuse the linker depending on the relative library versions.

When TARGET_PREFIX and TARGET_SYS didn't match up, the symlinks and
update-alternatives weren't working. TARGET_PREFIX is what we use when
configuring so it's what we should be using here.
This is 79b497edc0ce5d54db564818e59b690d3391d6ce from OE.

binutils.inc exports its own ${CC} which is similar to default ${CC}
but missing ${TOOLCHAIN_OPTION}, which makes --sysroot option lost
when compiling target binutils which then further breaks sstate.

Having one monolithic packages directory makes it hard to find things
and is generally overwhelming. This commit splits it into several
logical sections roughly based on function, recipes.txt gives more
information about the classifications used.
The opportunity is also used to switch from "packages" to "recipes"
as used in OpenEmbedded as the term "packages" can be confusing to
people and has many different meanings.
Not all recipes have been classified yet, this is just a first pass
at separating things out. Some packages are moved to meta-extras as
they're no longer actively used or maintained.
