Drop the old Sun-specific variants used in old workstations (pre-1997)
and other useless ones.
The V7 ISA is a very old cpu only used in the first Sun workstations,
the toolchain support is broken: the cpu doesn't do hardware div and
it's not handled elsewhere.
The sparclite is also a very old Fujitsu cpu only used in early 90s Sun
machines (includes f930 & f934).
The sparclet (tsc701) was a microcontroller-variant.
The supersparc and hypersparc are just V8 variants also used in old Sun
workstations/servers.

Except for architecture and processor names, buildroot uses capitalized
configuration names, so change the macro names for xtensa to follow that
standard.
Change the overlay file to have a subdirectory for each component
(gdb, binutils, gcc, etc.) to make it more future-prove.

Xtensa is a configurable processor architecture, which allows to define
additional instructions and registers. The required variant specific
information for the toolchain is delivered in an 'overlay' file, which
needs to be 'untarred' to the corresponding directories after the
source is installed and patched.
This patch provides support for binutils, gcc, and gdb with a very
limited changes to the build scripts. These additions are only executed
for the Xtensa architecture and have no effect on other architectures.

Variant'].

The Xtensa architecture had been removed because it required special
handling and depended on additional directories and files that became
obsolete over time. This change is more aligned to other architectures.

As suggested by Yann E. Morin, there is a better way than our current
big Config.in.common to define the gcc mtune, mcpu, march,
etc. values. We can split the setting of those values in each
architecture file, which makes a lot more sense.
Therefore, the Config.in file now creates empty kconfig variables
BR2_ARCH, BR2_ENDIAN, BR2_GCC_TARGET_TUNE, BR2_GCC_TARGET_ARCH,
BR2_GCC_TARGET_ABI and BR2_GCC_TARGET_CPU. The values of those
variables are set by the individual Config.in.<arch> files. This is
possible because such files are now only conditionally included
depending on the top-level architecture that has been selected.

target/Config.in.arch had become too long, and we want to remove the
target/ directory. So let's move it to arch/ and split it this way:
* An initial Config.in that lists the top-level architecture, and
sources the arch-specific Config.in.<arch> files, as well as
Config.in.common (see below)
* One Config.in.<arch> per architecture, listing the CPU families,
ABI choices, etc.
* One Config.in.common that defines the gcc mtune, march, mcpu values
and other hidden options.
